Title: Chemistry - Moles and pH
Post by: bufon1108 on March 20, 2005, 09:16:46 PM

Hello team:
Please I need help in a chemistry exercise:

How many mL of 0.10 M NaOH solution are needed to neutralize 15mL of 0.20 MH3PO4 solution?


Thanks in advance for your time and tips

Neutralization of H3PO4 can proceeds in three steps. You should specify which reaction you mean, eventually say , eg - complete neutralization.
Start from a balanced reaction.
