Howdy.


On #75, calculating the pH of a salt, if we see Na, K, Li, etc do we just assume these are "spectator ions" and don't include it in the reaction?


ALSO....this was suchhhh a lengthy mathematical problem...please tell me pH calculations on the real DAT aren't this crazy? I'm so bad with multiplying scientific notation numbers by decimals. lol..eeek

Thanks!

you won't have any crazy long calculation on GC section in DAT

pH calculations will be very mild for example: 1) what is the pH of 0.05 Ba(OH)2 which is 13 or what is the [H+] of pH of 4 which is 0.0001.
