Question

2. What chemical test(s) could you use to distinguish solid barlum chloride from solid barlum sulfate? 3. Do you think that washing soda, Na COs, could be used for the same purpose as baking soda, NaHCOs? Explain! 4. Write the chemical equations for the reaction of NaCO, with HCI and the reaction of NaHCO, with HCI 10 MacBook Ai

Answer 1

2.HCl(g) is produced and a precipitate is formed in the reaction of barium chloride.

BaCl₂(s) + H₂SO₄(l) $\rightarrow$ BaSO₄(s) + 2 HCl(g)

But in case of barium sulphate , no reaction occurs as seen by the reaction

BaSO₄(s) + H₂SO₄(l) $\rightarrow$ BaSO₄(s) + H₂SO₄(l)

3.Yes,baking soda could be used to same effect as washing as the same products will be formed.The only difference will be that since washing soda will consume two moles of acid,whereas baking soda will consume only one implying that washing soda is a stronger base which will cause the bitter taste of food products if washing soda is added instead of baking soda.

4.

Na₂CO₃(s) + 2 HCl(aq) $\rightarrow$ 2NaCl(aq) + H₂O(l) + CO₂(g)

NaHCO₃(s) + HCl(aq) -> NaCl(aq) + H₂O(l) + CO₂(g)
