How many liters of Cl2(g) at STP can be made from NaCl by oxidation with 24.0 grams of K2Cr2O7 in an acidic solution after chromium is reduced to Cr3+

6NaCl + K2Cr2O7 + 7H2SO4 = 3Cl2 + Cr2(SO4)3 + 3Na2SO4 + K2SO4+ 7H2

Step 1

Given,

Grams of K2Cr2O7 = 24.0 g

Moles of K2Cr2O7 can be calculated as:

Step 2

The balanced chemical reaction is given as:

6 NaCl + K2Cr2O7 + 7 H2SO4 → 3 Cl2 + Cr2(SO4)3 + 3 Na2SO4 + K2SO4+ 7 H2

From the reaction, it is evident that:

Step 3

The ideal gas equatio...
