# Calculating amount of alkali to change pH

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

Problem:

I have a 17,000 gallon tank of water and a weak acid (acetic acid to be specific); the tank has a pH of 4.4.

Using an alkali such as Na2CO3 (sodium carbonate) --- how much Na2CO3 is needed to raise the pH of this 17000 gallon tank from pH 4.4 to pH 4.8?

Thank you
