If the titration of h2po4− in a urine sample was continued until all of the acid in the solution was neutralized, how many equivalents of naoh would be needed to fully neutralize the solution?

Sagot :

Two equivalents of NaOH are needed to fully neutralize the solution.

What is a neutralization reaction?

A neutralization reaction involves the reaction of an acid and a base to form salt and water. The reaction is exothermic in nature.

For example,

[tex]HCl (aq) + NaOH(aq)\rightarrow NaCl(aq) + H_2O (l)[/tex]

During the titration of [tex]H_2PO_4^-[/tex] it gives [tex]2H^+[/tex].

[tex]H_2PO_4^- \rightarrow 2H^+ +PO_4^3^-[/tex]

To neutralize these [tex]2H^+[/tex], 2 [tex]OH^-[/tex] is needed which come from 2 equivalents of NaOH

[tex]2NaOH \rightarrow2 Na^+ +2OH^-[/tex]

Therefore, 2 equivalents of NaOH are needed
