Question

question 3 part a and b

Does the molar solubility of lead (II) iodide increase, decrease, or remain unchanged with the addition of potassium iodide to the solution? Explain. Experimental procedure, part A.4. What is the purpose of rinsing the pipet twice with saturated Ca(OH)_2 solution? Experimental procedure, Part A.4 What is the indicator used to detect the endpoint in the titration for this experiment ? What is the expected color change at the endpoint in this experiment? Experimental Procedure. Part A.5. The directions are to read and record the initial the correct number of significant figures. Explain what this means.

Explanation / Answer

What is the indicator used to detect the endpoint in the titration for this experiment

For detection of end point in iodine titration Starch indicator is used

Note- you have not described about the titration at all. But I have answered my question based on the above questions.

what is the expected color change at the end point of this titration

The titrant's solution turns blue-black when the endpoint has been reached in a titration using starch as an indicator
