g. Using the following equation 2 NaOH + H2SO4 2 H2O + Naso, How many grams of sodium sulfate will be formed if you start with 200 grams of sodium hydroxide and you have an excess of sulfuric acid?

Solution

2NaOH + H2So4 ------------> 2H2O + Na2So4

2 moles of NaOH react with excess of H2So4 to gives 1 mole of Na2So4

2*40g of NaOH react with excess of H2SO4 to gives 142g of Na2So4

200g of NaOH react with excess of H2So4 to gives = 142*200/2*40   = 355g of Na2So4 >>>>answer
