Question

Explain how you would obtain solid sodium carbonate from a mixture of lead carbonate and sodium carbonate powder

Answer 1

Swirl the reaction mixture gently and pour a little at a time

Answer 2

Dissolve the mixture in H2O; PbCO3 will not be soluble, filter and collect the PbCO3 as the solid. Use the filtrate, evaporate the water leaving solid Na2CO3.

Answer 3

add water to the mixture
stir to dissolved sodium carbonate
filter to obtain lead carbonate residue and sodium carbonate filtrate
wash and dry the residue

Answer 4

how to do sec

Answer 5

add H2o 2 de mixture stir 2 dissolve sodium carbonate filter to obtain PdCo3 as residue and NaCo3 filtrate wash ad dry th residue

Answer 6

advantages of rusting

Answer 7

1.It add nutrients to the soil
2.It controls land pollution by solid waste

Answer 8

Good thanks

Answer 9

You add H2O to the mixure,stir the mixture until it is disolved ,heat gently the solute substrate where by the H2O will subrime leaving the solid sodium carbonate
