In determining the Ksp of calcium Hydroxide lab
The lab report questions were

1. Predict how each of the following "mistakes" would affect the value of the measured Ksp by circling the correct response and providing reasoning for your response.

a) The buret was wet with water from cleaning.
The measured Ksp would be lower than the true value
The measured Ksp would be higher than the true value
The measured Ksp would be same as the true value

b) Using phenolphthalein as the indicator instead of methyl red.
The measured Ksp would be lower than the true value
The measured Ksp would be higher than the true value
The measured Ksp would be same as the true value

2. Write the solubility product expression for silver chromate.

3. If one has a solution of 0.10 M silver nitrate and it is diluted by a factor of 2, what is the new concentration?

4. If the dilution of 0.10 M silver nitrate by a factor of 2 is carried out five times, what is the final concentration?

5. The value for the Ksp of silver chromate is 1.1 X 10-12. In a saturated solution of silver chromate, the silver ion concentration is found to be 2.5 X 10-4. What must the chromate ion concentration be?
