In titrating the Ca(OH)2 filtrate. A student consistently went past the end point by about 2.0 mL every time. Will the measured Ksp be too big or too small?
|
Too big because the moles of OH– are overestimated. |
||
|
Too big because the moles of OH– are underestimated. |

|
Too small because the moles of OH– are overestimated. |

ALT CHEM 125 Name Determining the Ksp of Calcium Hydroxide Calcium hydroxide is an ionie solid that is sparingly soluble in water. A saturated, aqueous, solution of Ca(OH), is represented in equation form as shown below. Ca(OH)2 (5) --- Ca' (aq) + 2OH(aq) The solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and its dissolved ions in an aqueous system. The equilibrium expression for calcium hydroxide is shown below. Kp - [Ca][OHT...

Ksp of Ca(IO3)2 lab questions 1) Why is it necessary to filter the calcium iodate solution through dry filter paper, without adding any water? 2) If water had been added during the filtration process, how would this affect your calculated value for the Ksp of calcium iodate? Clearly explain whether your value would be too high or too low compared to the actual Ksp and why.
