Why doesn’t the KHP concentration have to be exactly 0.100M? Explain using complete sentences.
ollegr [7]

Answer:

The answer is in the explanation.

Explanation:

The KHP is an acid used as standard in titrations to find concentration of bases as NaOH.

The reaction that explain this use is:

KHP + NaOH → KNaP + H2O

<em>where 1 mole of KHP reacts per mole of NaOH</em>

That means, at equivalence point of a titration in which titrant is NaOH, the moles of KHP = Moles of NaOH added

With the moles of KHP = Moles of NaOH and the volume used by titrant we can find the molar concentration of NaOH.

The moles of KHP are obtained from the volume and the concentration as follows:

Volume(L)*Concentration (Molarity,M) = moles of KHP

If the concentration is more or less than 0.100M, the moles will be higher or lower. For that reason, we need to know the concentration of KHP but is not necessary to be 0.100M.

H3O+(aq) + OH-(aq) --> 2H2O (l)

NaHCO3(s) --> NaH 2+ (aq) + CO3 2- (aq)

NaH 2+ (aq) + H2O (l) --> Na+ (aq) + H3O+ (aq)

H2O (l) + CO3 2- (aq) --> OH- (aq) + HCO3- (aq)
