Question

what happened when the dilute HCl passed on NaHco3 write your observation​

Answer 1

Heelo

As we know that whenever any acid react with metal carbonate then it forms salt + carbon dioxide + water.

So when HCL reacts with nahco3 then the following reaction take place,

HCl + NaHCO3 = NaCl + H2O + CO2.

In this NaCl is salt which is also known as common salt and is used in cooking.

${\large{\purple{\mathbb{ANSWER}}}}$

When dil. Hcl(Hydrochloric acid) is passed on NaHco3 (Sodium Hydrogen Carbonate) then Nacl (Sodium Chloride, common Salt) Is formed along with H20 (Water) and Co2 (Carbon Dioxide).

Observation:-

• A gas is released with Brisk effervence (Co2) which can turn Lime water milky.

• Water is formed (H20).

• Common Salt is formed (Nacl).

Reaction:-

NaHco3 + Hcl ---> Nacl + H20 + Co2

Hope this will help you if it HELPS then plz mark my answer as BRAINLIEST.
