The reaction yields 2.76 grams of hydrochloric acid chlorine . water@--hydrochloric acid (aq-chloric acid (HCO) (aq) What is the theoretical yjeld of hydrochloric acid What is the percent yield of hydrochloric acid? grams Saicandy HOME END DEL NUM SPACE NONE

Explanation / Answer

3 Cl2(g) + 3 H2O(l) =======>   5 HCl(aq) + HClO3(aq)
Molar mass of Cl2 is 70.9 g/mol
Molar mass of HCl is 36.5 g/mol
From balanced reaction,
3 x 70.9 = 212.7 g of Cl2 react with water to give 182.5g of HCl
So, HCl produced from 4.87g of Cl2 reaction = 4.87 x 182.5 / 212.7
= 4.17g of HCl (theoretical yield or 100% yield)

Percent yield = 2.76 x 100 / 4.17
Percent yield = 66.19% or 66.2%
