Question

What effect does the concentration of H+(aq) ions have on the nature of the solution? 2. Name two nonmetals which will not displace hydrogen from dilute acids. (1+1)​

Answer 1

Answer:

ANSWER

(a) The concentration of H  

+

 (aq) ions determines the acidic nature of the solution. Hence, the acidity of a solution increases with increases in the concentration of H  

+

(aq) ions and vice versa.

(b) Yes, basic solutions also have H  

+

(aq) ions. They are basic because the concentration of hydroxide (OH  

−

) is more than the H  

+

(aq) ions.

(c) If the soil is acidic then it should be treated with quicklime or slaked lime to make it neutralize so that soil can be made proper for cultivation.

Answer 2

Solutions with higher concentration of H+ (aq) ions are strong acids. On the other hand solutions with lower concentration of H+ ions are weak acids

Reactive metals like zinc and sodium, for example, can displace hydrogen from dilute acids and form salts
