Question

If pH of any solution is equal to zero, then the solution will be:
A. Acidic
B. Basic
C. Neutral
D. None of these

Answer 1

Hint: pH is a measure of how acidic or basic a solution is. The pH runs from 0-14.A value of seven considers as it is a neutral solution, less than seven acidic and greater than seven basic. The pH is the negative logarithm of the hydrogen ion concentration. We can write the equation as,
     \[\Rightarrow {{p}{H}}=-{{\log }_{10}}[{{H}^{+}}]\]

Complete step by step answer:
We have given as pH=0, i.e. the negative logarithm of hydrogen ion concentration in that solution is equal to zero.
     \[\Rightarrow {{p}{H}}=-{{\log }_{10}}[{{H}^{+}}]=0\]
From this equation we have to find the concentration of hydrogen ion, i.e. taking anti-logarithm of 0 hence we get as,
     \[\Rightarrow [{{H}^{+}}]=1\]
It means the solution is strongly acidic, with a molarity of hydrogen ions equal to 1, i.e. 1 mole of [H+] ions per litre. So the given solution is acidic

Hence, the correct answer is option A.

Note:
The pH = 0, means that the number of hydrogen cations are of high concentration in the given solution. Some examples of solutions which are strongly acidic-$H_2SO_4$, HCl and so on. These acids show their concentration when mixed with water as relatively high.
