12. What is the concentration of the solution that results from diluting 75.0 mL of a 1.05 - solution of CH3OH to 500.0 mL? M. 1 13. How many grams of Ca(OH)2 are required to react with 2.36 mol of H3PO4 to prod Ca3(PO4)2 according to the equation ? 3Ca(OH)2 + 2H3PO4 +Ca3(PO4)2 + 6H2O
Ca3(PO4)2 and CaSO4 have certain solubility in water (they are not the same). Describe what happens to the solubility of each salt when each one is placed separately into 0.1000 M HCl. To obtain full credit, you must explain which salt shows the greatest change, if any, in solubility in 0.1000 M HCl. Assume you have an equal molar amounts of each salt and equal volumes of HCl. H3PO4: Ka1 = 7.5 x10-3 ; Ka2 = 6.2 x 10-8 ;...
