Homework Help: Chemistry

Posted by Trixie on Tuesday, March 16, 2010 at 7:46pm.

The pH of 0.50 M HBrO(aq) is 4.50. Calculate the change in pH when 6.50 g of sodium hypobromite is added to 110. mL of the solution. Ignore any change in volume. Ka of HBrO is 2E-9

I found the amount of moles used for each (.0547 mol NaBrO, and .055 mol HBrO soln)

I'm not totally sure how to find the new pH. Do I set up an ICE chart? If I do...I'm not sure how to set up the expression for the addition of NaBrO to HBrO...
