In a reaction, 5.3 g of sodium carbonate reacted with 6 g of acetic acid. The products were 2.2 g of carbon dioxide, 0.9 g water and 8.2 g of sodium acetate. Show that these observations are in agreement with the law of conservation of mass.
sodium carbonate + acetic acid `→` sodium acetate + carbon dioxide + water

Text Solution

Verified by Experts

The chemical reaction leading to products is
`"sodium carbonate"+"ethanoic acid" to "sodium ethanoate"+"carbon dioxide"+" water"`.
`"Mass of reactants" = (5:3+60)=11:3 g`
`"Mass of products"= (8:2 + 2:2 +0.9) 11:3g`.
The reactants and products have same mass. This means that there was no loss of mass during the reaction. Therefore, the data is in agreement with law of conservation of mass
