How many liters of 0.3m h3po4 are needed to neutralize 3.5l of 3m naoh

irga5000 [103]

Answer:

$V_{acid}=11.7L$

Explanation:

Hello,

In this case, given the reaction:

$3NaOH+H_3PO_4\rightarrow Na_3PO_4+3H_2O$

We notice a 3:1 molar ratio between sodium hydroxide and phosphoric acid, therefore, at the equivalence point we have:

$n_{base}=3*n_{acid}$

That in terms of molarity is:

$M_{base}V_{base}=3*M_{acid}V_{acid}$

Se we solve for the volume of acid:

$V_{acid}=\frac{M_{base}V_{base}}{3*M_{acid}} =\frac{3M*3.5L}{3*0.3M}\\ \\V_{acid}=11.7L$

Best regards.
