What is the correct order of the steps for this experiment? Gently boil the HCI/antacid tablet solution. Titrate with standardized NaOH until endpoint is reached. Dispose of all reagents in properly labeled waste containers. Add excess HCI to each tablet from a buret. Add 1-2 drops of phenolphthalein. Obtain two burets and prepare one for H CI and the other for standardized N a OH Obtain an antacid tablet and grind it a mortar and pestle. Weigh two small portions for two trials. (or obtain a pre-ground sample)

1. The reaction below will give us: a. 2b. 4c. 3d. 3 and 4e. 1

2.) Five standardized dilutions of aqueous lead(11) chromate solution were prepared by adding a volume of 0.0010 M PbCrO4(ag) from a buret and then diluting the solution with deionized water to a total volume of 100.0 mL. Use the provided information to determine [CrO42] in each. Hint: enter the decimal before the scientific notation.
