A) The Eriochrome Black T indicator is mistakenly omitted. What is the color of the analyte (standard Ca^2+ solution)?

Describe the appearance of the analyte with the continuedaddition of the Na^2H^2Y solution? Explain?

B) The Dispensing of the Na^2H^2Y solution from the buret isdiscountinued when the solution turns purple. Because of this technique error, will the reported molar concentration of theNa^2H^2Y solution be too high, too low, or unaffected?

C) The Dispensing of the Na^2H^2Y solution from the buret isdiscountinued when the solution turns purple. Because of this technique error, will the reported hardness of the water sample be too high, too low, or unaffected?
