Question

A 0.0035 M aqueous solution of a particular compound has pH = 2.46. The compound is (A) a weak base (B) a weak acid (C) a strong acid (D) a strong base (E) a salt

Answer 1

Answer:

(a) A strong acid

Explanation:

We have given the pH of the solution is 2.46

pH=2.46  

So the concentration of $H^+=10^{-pH}=10^{-2.46}=0.00346$

solution having H+ concentration more than $H^+=10^{-7}$ is acidic

Since in the given solution, H+ concentration is 0.00346 M which is more than 10^{-7}[/tex] so this is an acidic solution

Note-The concentration of $H^+$ decide the behavior of the solution that is, it is acidic or basic
