Question

If pH of strong acid is 0. 1gm H+ ions present in how many litre solution...? a) 1 b) 10 c) 0 d) 100​

Answer 1

Explanation:

The concentration of HCl in the solution is 1M. So, upon its dissociation, it will give 1M H+ ions. Now, this concentration of H+ ions will be useful in determining the pH of the solution.

The formula to find the pH of the solution is as below.

pH=−log10[H+]

We have already obtained that the concentration of H+ ions in the solution will be equal to 1M. So, we will put that value in the formula of pH. So, we get

pH=−log10[1]

Now, we can write 1 as 100 because 1=100. So,

pH=−log[100]

Now, we know that log[10x]=x. So,

pH=0

Thus, we obtained that pH of the 1M solution of HCl is 0
