Post by: organiclove on November 13, 2009, 01:44:27 AM

Using activities calculate the hydronium ion concentration and pH of a 0.12M solution of HNO2 that is also 0.050M in NaCl..

anyone mind pointing me in the right direction about what I need to do? i'm not really sure what im being asked, I'm horrible at analytical.. :(
