I'm not sure if i'm right but at least i can give you an idea. Since it says determine both the total volume of HCL and NaOH used in the titration,i think its asking you how much of the solution you used. so i subtracted 15.50 from 25.00 and i did the same for NaOH. so for HCL i got 9.50 and for NaOH i got 3.80.
and for number 10, i don't know if its right, but i think you have to use the titration equation and substitute. so for M(a) i put .10, for V(a) i put 5.00(because its asking for sodium hydroxide, so you use the NaOH column; the inital reading)and for V(b) i put 3.80 because that's how much was used. and the M(b)is blank because that's what you're supposed to look for.
for # 9 i am confuse on
ReplyDeletei am lost on # 10 i am confused about it

hope that wasn't confusing and it helped.
