please help I am having a difficult time answering these questions. I am submitting it as one because they are all related so please answer all of them. Fill in the entire table and then answer the following questions. please type the answers ( show all steps, states of matter for all equations.) all these questions are related to that pre-lab table. 1. Fill in the following table with the Ksp values for any insoluble salt that forms from a metal ion in the left column and the anions in the other columns. Some have already been provided for you. If a salt is soluble in water write N/A. a) Why were you unable to find some of the Ksp values for some ions? 2. In a test tube containing a precipitate of PbCrO4 in water: What are the concentrations of the lead (II) and chromate ions in equilibrium with the solid? Show your calculations. Use the Ksp from the Prelab table above . [Pb+2] = M [CrO4-2] = M 3. How can AgCl(s) be dissolved…

Preparation of 0.25N HCl Objective: Apparatus and Materials: Procedure: Compute for the volume of HCl needed to prepare 0L of 0.25N HCl. Using a graduated cylinder, measure the computed volume of HCl. Pour it into the volumetric flask that is half- filled with distilled water and agitate. Add enough distilled water until it reaches the mark. Transfer the solution to the reagent bottle. Add again distilled water until it reaches the mark and pour it to the same reagent bottle, thus making the total volume of 1.0L. Label the reagent bottle. Data and Computations: Conclusion:
