Answer
(a) Solution P
Reason — When alkalis are warmed with an ammonia salt, ammonia gas is given out.
(b) Solution R
Reason — Number 2 on pH scale represents a strong acid.
(c) Solution Q
Reason — As Q with pH 6 is a weak acid and will not be able to completely dissociate into ions. Hence, will have molecules and ions both.

When you use a universal indicator, you see that solutions of different acids produce different colours. Indeed, solutions of the same acid with different concentrations will also give different colours. Why?
You are supplied with five solutions : A, B, C, D and E with pH values as follows:
A = 1.8, B = 7, C = 8.5, D = 13, and E = 5
Classify these solutions as neutral, slightly or strongly acidic and slightly or strongly alkaline.
Which solution would be most likely to liberate hydrogen with:
(a) magnesium powder
(b) powdered zinc metal. Give a word equation for each reaction.
Select the word/s given below which are required to correctly complete the blanks — [ammonia, ammonium, carbonate, carbon dioxide, hydrogen, hydronium, hydroxide, precipitate, salt water] :
(i) A solution M turns blue litmus red, so it must contain (i) …………… ions ; another solution O turns red litmus blue and hence, must contain, (ii) …………… ions.
(ii) When solution M and O are mixed together, the products will be (iii) …………… and (iv) …………… .
(iii) If a piece of magnesium was put into a solution M,(v) …………… gas would be evolved.
Define the following and give two examples in each case : (a) a normal salt, (b) an acid salt, (c) a basic salt.
