3. A saturated solution of strontium hydroxide (Sr(OH)2) was analyzed using 0.10

3. A saturated solution of strontium hydroxide (Sr(OH)2) was analyzed using 0.10 M hydrochloric acid as the titrant. A 25.0-mL aliquot of the saturated solution required 21.0 mL of the HCl solution to reach the methyl orange endpoint. (Note: the chemistry is very similar to your experiment.) a) Write the chemical equation for the relevant solubility equilibrium (i.e. finish the following equation). Sr(OH)2(s) b) Write the net ionic equation related to the titration reaction. e) Calculate the number of moles of HCI added (i.e. the amount needed to reach the endpoint). d) Determine the number of moles of hydroxide ion in the sample of Sr(OH)2 solution analyzed. e) Calculate the molar concentration of hydroxide ion in the saturated solution. ) Calculate the molar solubility of strontium hydroxide.
