Question
1. Part A 2. Suppose some of the solid calcium hydroxide is inadvertently transferred along with the supernatant liquid for analysis. a. Will more, less, or the same amount of hydrochloric acid titrant be used for the analysis in Part A.6? Explain. b. Will this inadvertent transfer increase, decrease, or have no effect on the calculated solubility product for calcium hydroxide? Explain. c. Will this inadvertent transfer increase, decrease, or have no effect on the calculated molar solubility of calcium hydroxide? Explain.Explanation / Answer
Ca(OH)2 + 2HCl ---------------> CaCl2 + 2 H2O
A) the amount of SOLID CALSIUM HYDROXIDE IS TAKEN FOR TITRATION IN PART A , INADVERENTLY TRANSFEERED TO the flask, then whatever the amount of traansferred Ca(OH)2 IN the titration flask it requires the same amount as the calsium hydroxide, But 2 moles of HCl is required, as per the reaction shown above,
whatever the wt . taken it doesnt affect the titration in this case, but if you have calculated the wt of HCL REQUIRED BASED ON ORIGINAL WT. THEN LESS AMOUNT OF HCL IS REQUIRED THAN CALCULATED.
B) THIS TRANSFER DECREASE THE CALCULATED SOLUBLITY OF Ca(OH)2.
(C) THIS TRANSFER OF CALSIUM HYDROXIDE SUPERNATANTLY, DECREASES THE MOLAR SOLUBLITY,
BECAUSE CALCULATED WT OF Ca(OH)2, NOT TOTALLY TRANSFERRED TO THE FLASK.
