Title: INORGANIC CHEM HIGH SCHOOL
Post by: APPLE on November 24, 2020, 03:29:21 PM
Can anyone solve this two problems ?
1.The sample containing hydroxide, carbonate and  sulfate of Ca (calcium) weighs 31 g. It was treated with dilute hydrochloric acid. This released 2.24 dm3 of gas, leaving 13.6 g of undissolved residue. Determine the mass of the components of this sample.
2.the unlabeled reagent bottles contain sodium carbonate, calcium carbonate, barium sulphate, sodium chloride and sodium sulphate, how with distilled water, dilute HCl and barium chloride solution can determine what is in which reagent bottle.Show with reactions with aggregate states.
THANK YOU SO MUCH!!!!!
