What can an experiment to use to distinguish between a strong acid and a strong base

aivan3 [116]

The pH meter can only be used to differentiate between weak and strong acids providing that the concentrations are known. However, it is convenient to determine the concentration of an acid (or base) by titration.

What is the pH of a solution with a concentration of 5.2 × 10–8 M H3O+?

lora16 [44]

Answer : The pH of a solution is, 7.28

Solution : Given,

Concentration of hydronium ion, $H_3O^+$ = $5.2\times 10^{-8}M$

pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.

$pH=-\log [H_3O^+]$

Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.

$pH=-\log (5.2\times 10^{-8})=7.28$

Therefore, the pH of a solution is, 7.28
