Question

When we pour phenolphthalein into solution A it turns pink and if we add solution B into it it turns colourless write down the PH range of solution A and solution B?​

Answer 1

Answer:

(a) Acids are : HCl and lemon juice because the pH is less than 7.

(b) Alkaline or basic solution turns phenolphthalein pink.

(c) Neutral solutions : Distilled water and NaCl.

(d) HCl is the strongest acid and NaOH is the strongest base.

Answer 2

Answer:

pH of solution A is from 8 to 14 and B is from 0 to 6(7 is neutral)

Explanation:

Since Solution A turns pink it is BASIC solution so it will have pH from 8 to 14 and as solution B turns

to be colorless it is ACIDIC solution this will have pH ranging from 0 to 7.
