Question

Metal sulfites, such as Na2SO3, also react with HCl to produce a gas than escapes from the reaction mixture. For example: Na2SO3+ 2 HCl -->2 NaCl + H2O + SO2(g)

 

Which reaction below would result in the production of more mass of gaseous product?

 

The reaction of 1.0 g Na2CO3 with excess HCl to produce CO2(g)

The reaction of 1.0 g Na2SO3with excess HCl to produce SO2(g)

Answer 1

1.0 g Na2CO3 x 1 mol/106 g = 0.009 moles CO2 x 44 g/mole = 0.40 g CO2

1.0 g Na2SO3 x 1 mol/126 = 0.008 moles SO2 x 96 g/mole = 0.77 g SO2

Can you tell which one results in the production of more gas?

 

If you wanted to do this on the basis of % composition, you could do it that way also.
