Which one will not change from red litmus to blue?a) NaClb) HClc) KOHd) LiOHCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Option b is correct. Because, as the HCl is an acid and the colour of the litmus is already is Red. If there is a presence of acid, then we need the Blue colour litmus paper which turns into Red colour litmus paper due to the presence of acid.

As per the option says, option c, d are already Bases due to the presence of OH- ions as you can see the options. Option a is not neither acid or base. It is neutral in nature as it's pH is 7.

Option c, d needs Red colour litmus paper which turns into Blue colour litmus paper due to the presence of OH-ions which indicates themselves as they are bases.

Hope you have understand the concept friend..

Answer

Ur answer is wrong,because hcl is an acid and acid change blue litmus to red ..and correct answer is KOh..

Answer

Correct answer is B because a base can only change a red litmus to blue in colour.But in the question they have given that which one will not change red litmus to blue which means that which will change red litmus to red itself.So an acid can only change red litmus to red itself. So in these only HCL is the acid so it will change red litmus to red itself..

Answer

KOH nd LiOH are base bcoz it release OH in aqueous solution.
so the red litmus change into blue shows that the substance is ab base

Answer

It's an acid, the red litmus paper indicates the presence of an acid.

Answer

The correct option is (b)  HCL because as we know red litmus turns blue in presence of base and as HCL is a acid to it doesn't change red litmus to blue.  Hope it is helpful.

Answer

Your answer option B is wrong  because acid donot change the red litmus in blue .Acid change only blue litmus into red.only base are change red litmus into blue .   KOH and LIOH are a base so ,it change red litmus in blue .

Answer

Option c is correct not option b as HCl is acid and acid turns blue litmus to red not red litmus to blue

Answer

Explanation:

Introduction:
Red litmus paper is used to test for acids. When an acid reacts with red litmus paper, it turns blue. However, not all substances will cause red litmus paper to change color. In this case, we are given four options and we need to determine which one will not change from red litmus to blue.

Explanation:
To determine which substance will not change from red litmus to blue, we need to understand the nature of each option.

a) NaCl (Sodium Chloride):
- Sodium chloride is a compound formed by the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl).
- Both sodium hydroxide and hydrochloric acid are strong bases and acids respectively, and they can turn red litmus paper blue.
- Therefore, sodium chloride will also turn red litmus paper blue.

b) HCl (Hydrochloric Acid):
- Hydrochloric acid is a strong acid and can turn red litmus paper blue.
- Therefore, HCl will turn red litmus paper blue.

c) KOH (Potassium Hydroxide):
- Potassium hydroxide is a strong base and can turn red litmus paper blue.
- Therefore, KOH will turn red litmus paper blue.

d) LiOH (Lithium Hydroxide):
- Lithium hydroxide is a strong base and can turn red litmus paper blue.
- Therefore, LiOH will turn red litmus paper blue.

Conclusion:
From the given options, only option B (HCl) will not change from red litmus to blue. Hydrochloric acid is a strong acid and therefore does not have the ability to turn red litmus paper blue.

Answer

Yes b) HCl is right answer because HCl is acid it is change blue litmus to red .Nacl is salt and and KoH are base
