How do I figure this question out?"how many moles of lead (II) nitrate are needed to react completely with 25.50 moles of potassium chromate?"
qualitative analysis lab was conducted for 8 cations (chromium, copper, barium, iron, lead, Manganese, Nickel, silver) using NaCl to identify type I, NH4OH to identify type II and type III was determine when they were not type II. Then the verification procedure was perform to identify the...
Read the lab procedure attached, and please answer the question. Why was it necessary to add HCl to the mixture of cations at the beginning of the separation process? Why was it necessary to avoid adding too much HCl during this first step? After the HCl was added to the mixture, the mixture was...
