Relating to titration problems: How do you know when it is appropriate to use either the neutralization reaction, the hydrolysis reaction, or the stoichiometry reaction?
I am trying to figure out when I can use the ICE table, or when I am supposed to use stoichiometry to solve at different points in a reaction. Please explain the concept behind your answer as well.
If it helps to apply your explanation to a problem: TItration of 10mL of 0.3 M NH3 with 0.1 M HCl. Find the pH at the addition of 0.0mL of HCl, 10mL of HCl, 20mL of HCl, 30mL of HCl, and 40 mL of HCl. I do not need the answer to this problem. However, if it helps you to explain, then feel free.
Thank you!

In this experiment you will use an oxidation - reduction titration to determine the percent of oxalate ion, CO2 in an unknown sample containing oxalate ion. Potassium permanganate (KMnO.) will be titrated against the oxalic acid (C2H:08) as shown by the following oxidation-reduction reaction: +3 +7 5C,044 2MnO4 + 16H* → 10CO, 8H0 + 2Mn2 +4 + + Mno. Mn? is the reduction process C2042 → CO2 is the oxidation process The underlying principle behind a titration is that an...

Can someone walk through a few simple algebraic solution-making problems? I know how to use formulas, such as C1V1 = C2V2, however I'm having issues with the conceptual part, mostly for when using two solutes. Problem #1: Make 200 mL of a saline that has 5 mMol NaCl and 15 mMol KCl. Stocks are 0.1 M NaCl & 0.2 M KCl. (and if it's simply the C1V1=C2V2 of one, and then the second, added together in a 200 mL flask...
