After isolating and precipitating the magnesium salt A, a portion was dissolved in distilled
water in order to make a 250.0-mL saturated solution. The titration of a 50.0-mL aliquot
of the saturated solution required 8.20 mL of HCl titrant to reach the phenolphthalein
endpoint.
Meanwhile, dissolving this magnesium salt in 250.0 mL of 0.0200 M MgClz required 1.51
mL of the same HCI titrant to titrate a 100.0-mL solution.
