Determine the oh of a solution that is 0.220 m in hco3

ICE Princess25 [194]

Answer : The hydroxide ion concentration of a solution is, $5\times 10^{-14}$

Explanation :

As we know that $HCO_3^-$ dissociates in water to give hydrogen ion $(H^+)$ and carbonate ion $(CO_3^{2-})$ .

As, 1 mole of $HCO_3^-$ dissociates to give 1 mole of hydrogen ion $(H^+)$

Or, 1 M of $HCO_3^-$ dissociates to give 1 M of hydrogen ion $(H^+)$

So, 0.200 M of $HCO_3^-$ dissociates to give 0.200 M of hydrogen ion $(H^+)$

Now we have to calculate the hydroxide ion concentration.

As we know that:

$[H^+][OH^-]=1\times 10^{-14}$

$0.200\times [OH^-]=1\times 10^{-14}$

$[OH^-]=5\times 10^{-14}$

Therefore, the hydroxide ion concentration of a solution is, $5\times 10^{-14}$
