Synthesis of Alum (Potassium Aluminum Sulfate) from Aluminum Aluminum cans can be recycled to make potassium aluminum sulfate dodecahydrate, KAK(SO)12H20, which is abbreviated to "alum". The 12 waters are part of the overall formula. Alum can be used to make dyes, printing fabrics, making paper, adhesives, pickling of food and vets use it to induce a dog to throw up. x 1 rxn 2 run 3 The following are the four reactions that lead to alum: Al(s) + 2 KOH...

My question I need help with though is:
This is my data and what I have so far but this is the
question I actually need help with:
-What ions are present in the titrated solution after the
beginning of the titration but before the equivalence point? How
about after the equivalence point when the conductivity is rising?

CH 111 - Introduction to Inorganic and Organic Chemistry Lab 10 - Exp. 341 Synthesis of Strontium lodate In this lab, we will perform a synthesis reaction to generate a desired product. Synthesis reactions are performed in many different industries including fertilizers, plastics, pharmaceuticals and many others. The goal in a synthesis reaction is to generate and obtain as much of the desired product as possible. In this synthesis, the reaction between KIO, (potassium iodate) and Sr(NO3)2 (strontium nitrate) produces...
