Homework Help: chemistry steps check

Posted by Amy on Friday, May 2, 2008 at 11:45pm.

What is the pH of the solution created by combining 11.10 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)?

This is exactly like what Dr Bob has shown me on the first problem i put here and yet i get this simple one wrong...


Here are my steps:

NaOH: 0.0111L x.1 M= .00111 moles
HCl: 0.008L x .1M=.0008 moles

.0011- .0008= .0003

.0003/ .0191= .0157

pH= -log (.0157)= 1.80
