- Determine the lime and soda ash does, in mg/L as CaO and Na2CO3, to soften the Thames River to a final hardness of less than 125 mg/L as CaCO3. Assume that all the alkalinity is bicarbonate and that the lime is 90% pure and the soda ash is 97% pure. (4.21)arrow_forward100.0 mL of HCI required 5.831 g Mg(OH)2 to titrate. The molar mass of Mg(OH)2 is 58.31 g. What is the concentration of the HCI ? The neutralization equation is 2 HCI + Mg(OH)2 MgCl₂ + 2 H₂O There is enough information to calculate the moles of Mg(OH)2 mol Mg(OH)2 -): (5.831 g Mg(OH)₂ (- g Mg(OH)₂ Then use stoichiometry to convert moles of Mg(OH)2 into moles of HCI mol HCI concentration a. acid i. 0.2000 mol Mg(OH)2 (-- mol Mg(OH)2 We now can calculate the concentration of HCI since we have both the moles of HCI and the volume of HCI mol HCI p. 0.01000 b. base c.
