A few drops of concentrated HCI are added to about 10cm3 of a solution of pH 3.4. The pH of the resulting mixtures is?
less than 3.4
greater than 3.4
unaltered
the same as that of pure water
Correct answer is A
The addition of concentrated HCl to the solution makes the solution more acidic and the pH falls below the original value that is the pH value of the solution will now be less than 3.4.
