Trisodium phosphate (TSP) is a commonly used ingredient in soap powders due to its various properties that enhance the effectiveness of the soap. The main use of TSP in soap powders is to make the soap act rapidly. Let's explore why TSP is used for this purpose:

1. Enhanced Cleaning Power:
- TSP is an alkaline compound that helps to increase the pH of the soap powder. This alkalinity enhances the cleaning power of the soap by breaking down grease, oils, and other stubborn stains.
- The high alkalinity of TSP helps to dissolve and remove dirt and grime effectively, allowing the soap to act rapidly and provide efficient cleaning.

2. Softening Hard Water:
- TSP has the ability to soften hard water by binding to the minerals present in the water, such as calcium and magnesium ions. This prevents the minerals from interfering with the soap's ability to lather and clean effectively.
- Hard water can reduce the effectiveness of soap by forming insoluble salts with fatty acids, resulting in soap scum and reduced lathering. By softening hard water, TSP ensures that the soap can lather well and clean efficiently.

3. pH Adjustment:
- TSP is also used to adjust the pH of soap powders. Soap generally works best in slightly alkaline conditions, as alkalinity helps to break down dirt and grease.
- By adjusting the pH to a suitable alkaline range, TSP ensures that the soap can act rapidly and effectively under optimal conditions.

4. Stabilizing Properties:
- TSP has stabilizing properties that help to prevent the soap powder from separating or deteriorating over time. It helps to maintain the consistency and quality of the soap powder, ensuring that it remains effective for a longer period.

In conclusion, trisodium phosphate (TSP) is used in soap powders to make the soap act rapidly by enhancing its cleaning power, softening hard water, adjusting the pH, and providing stabilizing properties. These properties make TSP a valuable ingredient in soap powders, ensuring efficient cleaning and a superior performance of the soap.

Read the passage given below and answer the following questions:The amount of moisture that leather adsorbs or loses is determined by temperature, relative humidity, degree of porosity, and the size of the pores. Moisture has great practical significance because its amount affects the durability of leather, and in articles such as shoes, gloves and other garments, the comfort of the wearer. High moisture content accelerates deterioration and promotes mildew action. On the other hand, a minimum amount of moisture is required to keep leather properly lubricated and thus prevent cracking. The study indicates that adsorption of moisture by leather is a multi- molecular process and is accompanied by low enthalpies of adsorption. Further at 75-percent relative humidity, the adsorption is a function of surface area alone. Untanned hide and chrome- tanned leathers have the largest surface areas. The leathers tanned with vegetable tanning materials have smaller surface areas since they are composed of less hide substance and the capillaries are reduced to smaller diameters, in some cases probably completely filled by tanning materials. This process of tanning occurs due to mutual coagulation of positively charged hide with negatively charged tanning material. The result of the study indicated that untanned hide and chrome-tanned leather absorb the most water vapour.In these questions a statement of Assertion followed by a statement of Reason is given.

Read the passage given below and answer the following questions:EVIDENCE FOR THE FIBROUS NATURE OF DNAThe basic chemical formula of DNA is now well established. As shown in Figure 1 it consists of a very long chain, the backbone of which is made up of alternate sugar and phosphate groups, joined together in regular 3’ 5’ phosphate di-ester linkages. To each sugar is attached a nitrogenous base, only four different kinds of which are commonly found in DNA. Two of these---adenine and guanine--- are purines, and the other two thymine and cytosine-are pyrimidines. A fifth base, 5-methyl cytosine, occurs in smaller amounts in certain organisms, and a sixth, 5-hydroxy-methyl-cytosine, is found instead of cytosine in the T even phages. It should be noted that the chain is unbranched, a consequence of the regular internucleotide linkage. On the other hand the sequence of the different nucleotides is, as far as can be ascertained,completely irregular. Thus, DNA has some features which are regular, and some which are irregular. A similar conception of the DNA molecule as a long thin fiber is obtained from physicochemical analysis involving sedimentation, diffusion, light scattering, and viscosity measurements. These techniques indicate that DNA is a very asymmetrical structure approximately 20 A wide and many thousands of angstroms long. Estimates of its molecular weight currently center between 5 X106and X107(approximately 3 X104nucleotides). Surprisingly each of these measurements tend to suggest that the DNA is relatively rigid, a puzzling finding in view of the large number of single bonds (5 per nucleotid e) in the phosphate-sugar back bone. Recently these indirect inferences have been confirmed by electron microscopy.Q. DNA has a ___________ backbone

Read the passage given below and answer the following questions:Adenosine triphosphate (ATP) is the energy carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually only the outer phosphate is removed from ATP to yield energy; when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates.The importance of ATP (adenosine triphosphat e) as the main source of chemical energy in living matter and its involvement in cellular processes has long been recognized. The primary mechanism whereby higher organisms, including humans, generate ATP is through mitochondrial oxidative phosphorylation. For the majority of organs, the main metabolic fuel is glucose, which in the presence of oxygen undergoes complete combustion to CO2 and H2O: C6H12O6 + 6O2 → 6O2 + 6H2O + energyThe free energy (ΔG) liberated in this exergonic (ΔG is negative) reaction is partially trapped as ATP in two consecutive processes: glycolysis (cytosol) and oxidative phosphorylation (mitochondri
