Writing a balanced equation
« on: July 24, 2009, 01:55:34 AM »
NH4Br has been dissolved into 1 L of water at 25 degrees celcius. the solution has a pH of 5.16. calculate number of grams of NH4Br.

I dont even know how to write the equation for this. Could someone please write the water + NH4 equation for me. Thanks :)
