**[Urgent] Titration Problem!**

## Homework Statement

Titrate 60ml of .15M of HNO3 with .45M NaOH.

A) Give pH of Initial Point.

B) Give pH of Equivalent Point.

C) Give pH of Mid Point.

D) Give pH of End point.

## Homework Equations

nacid=nbase

## The Attempt at a Solution

A) I think I did this right.

HNO3-> H + NO3

Strong Acid = 100% dissociated

pH= .8

B)nacid=nbase

(.15M)(.06L)=(.45M)x L

= .02L~20ml

C) I'm stuck here. Strong acid+ strong base = 1/2 neutralization.

?/(.06+.02/2) =

I don't get how I get the top part of that equation. The answer was said to be, .064M H+. pH = 1.2.

D) Strong Acid + Strong Base = H20, pH = 7.

Please help! I have a test this tuesday.
