Homework Help: Advanced Chem

Posted by Katie L on Tuesday, April 22, 2008 at 5:07pm.

What would be the pH of a mixture of 50.0 mL of 0.0614 M HI and 75.0 Ml of 0.0845 M NH4NO3??

When i worked this question out, i got a basic pH of 12.42!! But I know that's not right b/c its a strong acid mixed with a weak acid (i think NH4NO3 is a salt of a reaction; i know it's midly acidic).

Can you please walk me through the steps so I can find out where my calculations went wrong?? Thank you so much!
