Question

Calculate the h3o+ ion concentration of water sample having ph 6.58

Answer 1

Answer : The concentration of $H_3O^+$ ion of water sample is, $3.8\times 10^{-6}$

Solution : Given,

pH = 6.58

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

Formula used :

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

Now put the value of pH, we get the $H_3O^+$ ion concentration of water sample.

$6.58=-\log [H_3O^+]$

$[H_3O^+]=3.8\times 10^{-6}$

Therefore, the concentration of $H_3O^+$ ion of water sample is, $3.8\times 10^{-6}$
