Hello,(adsbygoogle = window.adsbygoogle || []).push({});

Im am working on my grade 12 chemistry course ALMOST DONE YEAHH!

I am stuck ona few questions, and Im hoping to get some help even if you just tell me where to begin on solving these.

1) If the [tex]Ka=1.8 * 10^{5}[/tex] for acetic acid ( ie. [tex]CH_{3}COOH[/tex]), what is the [tex]H^{+}[/tex] ion concentration in a solution of this acid, if 1.2 grams of acid are dissolved in 1.0L of solution.

Is there a formula i should be using to solve this question I cant seem to figure out what I am supposed to be doing.

I know Im going ot get told, I have to show my work so far but thats just the problem I have no clue where to begin, so if someone could just help me with that, I am not asking for you to do the question for me.

2. An electrochemical cell is constructed by placing a nickel electrode into a 1.0 M [tex]NiSO_{4}[/tex] solution, and a silver electrode into a 1.0 M [tex]AgNO_{3}[/tex] solution, and then joining them with a salt bridge to complete the circuit.

a) give the anode half reaction and the E[tex]^{o}[/tex] value.

b) give the cathode half reaction and the E[tex]^{o}[/tex] value.

c) Give the net reactiona nd its E[tex]^{o}[/tex] value.

What I am able to find out is The Eo value of Ag+ is +0.80 ans the Eo value of Ni2+ is -0.24> But other than this I am completely clueless as where to solve the question

PLEASE HELP!
