Question

The pH of 10^ -11 M HCl at 25°C is: (1)11, (2)3, (3) slightly greater than 7, (4) slightly less than 7

Answer 1

4. ( slightly less than 7.)

this can be seen as the acid will give very less H+ ions but at the same time water can also loose H+ ion ( concentration of H+ loosed by water is

${10}^{ - 7 }$

so total concentration will be more than this and ph will less than 7.

Answer 2

The pH of the solution is 11

Explanation:

We are given:

Molarity of HCl = $10^{-11}M$

1 mole of HCl produces 1 mole of $H^+$ ions and 1 mole of $Cl^-$ ions

To calculate the pH of the solution, we use the equation:

$pH=-\log[H^+]$

We are given:

$[H^+]=10^{-11}M$

Putting values in above equation, we get:

$pH=-\log(10^{-11})\\\\pH=11$
