7-11. Limestone consists mainly of the mineral calcite, CaCO3. The carbonate content of 0.541 3 g of powdered limestone was measured by suspending the powder in water, adding 10.00 mL of 1.396 M HCl, and heating to dissolve the solid and expel CO2: CACO3 (s) +2H* → Ca²+ +CO,↑ +H2O Calcium carbonate FM 100.086 The excess acid required 39.96 mL of 0.100 4 M NaOH for complete titration to a phenolphthalein end point. Find the weight percent of calcite in the limestone.

5. Erina observed that the borax she uses to clean the house is only partially soluble with water. She found on the internet that borax is composed of sodium tetraborate (Na,B,0;(OH), • 8H,0) and wanted to analyze its solubility. The dissolution of borax is: Na,B,0;(OH), • 8H20(9 = 2 Na (aq) + B40;(OH), (aq) + 8 H20o A 50.0 mL saturated solution was prepared for the experiment. After filtering the solution, a 5.00 mL aliquot was transferred to a 25.0 mL Erlenmeyer flask and was titrated using pre-standardized 0.4320 M HCI. The endpoint was reached after the addition of 4.73 mL titrant. Since the tetraborate anion (B,0;(OH),?) is a weak base, the tetraborate ion reacts with HCI by the reaction: B,0,(OH), (aq) + 2 H*(aq) + 3 H,0g = 4 H;BO3(aq) a. Write the K, expression for the dissolution process.

Sodium nitrate contains 0.3% iodine in the form of calcium iodate, Ca(IO3)2. After the sodium nitrate in the niter is dissolved and recrystallized, the remaining solution contains 9 g/Lsodium iodate, NaIO3(aq). The NaIO3 is converted to iodine when it reactswith sulfur dioxide and water.2NaIO3 + 5SO2 + 4H2O → Na2SO4 + 4H2SO4 + I2a.
