2) You are presented with an unknown that possibly has Ag-, Bi-, Sn+, Zn2+, Co2+ and Na'. You divide the solution into three equal volumes, labeling one "A," one "B," and one "C." To "A" you add 6 M HCl and do not observe any precipitate forming. In tube B, you add 6 M HCl until the pH is 0.5 then add thioacetamide and heat the solution in a hot water bath for seven minutes, eventually observing a black precipitate....

Solve question 3 Only, Be very clear/ about evry single
step
Mark all currents/ voltages
assign label and polarity
redraw simplified circuits
then write KVL and KCl equations dont use values, write plain
equations first then apply Ohms law.
Substitute values last. in equations
solve equations for unknowns show step by step solution for
each unknown.
write clearly. evry step.

2. How many mL of 0.100M NaOH would you need to titrate if you measured out 0.120 g of oxalic acid? Must show calculation. (5 pts) lying an unknown acid Objective: Identify an unknown diprotic acid by determining its molecular weight. Introduction: A diprotic acid is an acid that yields two H ions per acid molecule. Therefore, two moles of NaOH are need to react with every one mole of diprotic acid. The net reaction of a diprotic acid, H:X,...
