If significantly less then 25.00 mL of acid were added to the flash in step 7 of the procedure, what affect would this have on the accuracy of the sodium hydroxide concentration? Explain your answer

Respuesta :

Answer:

The concentration of the base will be lower than the exact one.

Explanation:

Hello,

In this case, in neutralization processes, the following equation is used:

[tex]n_{acid}=n_{base}[/tex]

It means that the moles of acid equal the moles of base at the equivalence point and in terms of volumes and concentrations is:

[tex]C_{acid}V_{acid}=C_{base}V_{base}[/tex]

In such a way, by decreasing the volume of acid, the computed or estimated concentration of the base will be lower than the original value. for that reason, accurate procedures must be performed.

Regards.
