Which of the following statements is/are correct?1. All bases are alk...
All bases are alkali:
- This statement is incorrect. Bases are compounds that can accept a proton (H+) or donate a pair of electrons. Alkalis, on the other hand, are a specific type of base that dissolve in water to form hydroxide ions (OH-) as the only negative ion. Therefore, while all alkalis are bases, not all bases are alkalis.
All alkalis dissolve in water:
- This statement is correct. Alkalis are a type of base that readily dissolve in water. When alkalis dissolve in water, they release hydroxide ions (OH-) into the solution. Examples of alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Alkalis are soapy to touch, bitter in taste, and corrosive in nature:
- This statement is also correct. Alkalis exhibit certain physical and chemical properties. Some of these properties include:
- Soapy to touch: Alkalis have a soapy or slippery feel when touched. This is due to the reaction of alkalis with the fatty acids present in the skin, which forms soap-like substances called salts of fatty acids.
- Bitter taste: Alkalis have a bitter taste. This taste is due to the basic nature of alkalis, which can neutralize and react with the acidic taste buds on the tongue.
- Corrosive nature: Alkalis are corrosive in nature. They have the ability to react with and corrode certain materials. For example, alkalis can react with metals, such as aluminum and zinc, to produce hydrogen gas. They can also cause burns and damage to living tissues.
Conclusion:
- Based on the above explanations, statement 2 and 3 are correct. All alkalis dissolve in water, and alkalis are soapy to touch, bitter in taste, and corrosive in nature. Therefore, the correct answer is option C, which states that statements 2 and 3 only are correct.

Which of the following statements is/are correct?1. All bases are alk...
A base is a substance which is bitter in taste, turns red litmus paper blue, gives hydroxyl ions (OH–) in aqueous solution, can accept a proton, and can donate electrons. Oxides and hydroxides of metals are bases. Water-soluble bases are called alkalis. All alkalis are bases, but all bases are not alkalis because all bases are not soluble in water. The pH of a solution is the negative logarithm of the concentration of hydrogen ions in mole per litre.
So, option c is correct.
