Purpose ● The purposed of the lab is to lets us student know if we know how calculate the percent yield of a double displacement reaction while using the grams that we get from our lab. Objectives ● We need to know the solid precipitate that had been formed in the

CHEM111AC‚ Experiment#9 - Ionic Reactions Discussion/Error Analysis In the first part of this experiment‚ the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another. For solution A: mixing A + B formed a precipitate‚ A + C generated heat‚ A + D gave no reaction‚ A + E gave no reaction‚ A + F gave no reaction‚ A + G formed a precipitate. For solution B: mixing B

group of four reactions‚ Iron phosphate and calcium phosphate are the two products that are insoluble in water. In the three of the four reactions a cloudy white or yellow formed. This indicated the formation of a precipitate‚ caused by the generally insoluble phosphate anion. Potassium chloride‚ Iron nitrate‚ and potassium sulfate where the products which were soluble in water. With these products there was no evidence of a precipitate forming. 2. Based on the results from reactions A and B for

Malacanang has declared February 25 as a special holiday for all schools nationwide. People Power Day or Araw ng People Power is a school holiday. This is in commemoration of the 1986 People Power Revolution. Senator Gregorio Honasan‚ a former rebel soldier‚ was one of the major figures in the 1986 EDSA Revolution.
