10 mL of 10 % sodium sulphate solution into a clean test tube. Add 1 drop of 10 % barium chloride. What do you observe? Write an equation to explain your observations in your lab report. C2. Measure out a fresh 10 mL portion of 10 % sodium sulphate into another test tube. Making sure to count the drops,
10 mL of 10 % sodium sulphate solution into a clean test tube. Add 1 drop of 10 % barium chloride. What do you observe? Write an equation to explain your observations in your lab report. C2. Measure out a fresh 10 mL portion of 10 % sodium sulphate into another test tube. Making sure to count the drops, use a dropper to add 30 % calcium chloride solution. Swirl the solution after each drop. Continue until a white precipitate occurs. Write an equation to explain your observations. Which solubility product has the smaller numerical value, that for calcium sulphate or barium sulphate? Explain how you know this is true. C3. Measure out another 10 mL portion of 10 % sodium sulphate into a clean test tube. Add 8 drops of 50 % sulphuric acid and swirl. Count the number of drops (swirl after each drop) of 30 % calcium chloride needed to produce a precipitate of calcium sulphate. Explain why the number of drops of calcium chloride differs in the two experiments. I need equations, observations and explanations
