Why is there bubbles on the surface of dilute H2SO4 reacting with limestone, it stops after a while

The two first produce calcium sulfate, and calcium sulfate is slightly soluble, it will wrap on the surface of the limestone, isolate the limestone and sulfuric acid, and the tissue reaction continues. So it started to bubble and it stopped after a while.

Sulfuric acid and limestone produce calcium sulfate.

Calcium sulfate is slightly soluble in water so the product coats the limestone surface.

Prevented the reflection from proceeding.

H2SO4 + CaCO3 ===CaSO4 (slightly soluble) + H2O + CO2

Since CaSO4 is a microsoluble. It coats the surface of the limestone and prevents H2SO4 from reacting with CaCO3 contact.

The resulting calcium sulfate microsolubles cover the limestone, preventing the reaction from continuing.

The CaSO4 produced by the reaction of CaCO3, the main component of H2SO4 limestone, is insoluble in water, covering the surface of the limestone, preventing the reaction from continuing!

CaCO3+H2SO4 (dilute) CaSO4 (slightly soluble) H2O+CO2, CaSO4 covers the limestone surface and prevents the reaction from proceeding.

The product coats the limestone surface and prevents the reaction from proceeding.

h2so4+caco3===caso4+h2o+co2↑

The calcium sulfate produced in this reaction is a microsoluble. It will adhere to the surface of the limestone, making it difficult for the reaction to proceed, so the reaction will stop

Because the resulting calcium sulfate is slightly soluble in water, it adheres to the surface of the limestone, preventing the reaction from proceeding further!

Ask your chemistry teacher, and he'll say the same thing.

Ca(OH)2+2HCl=CaCl2+2H2O, the reaction generates water, the reaction phenomenon is not obvious, it should be the reaction of limestone and dilute hydrochloric acid, such as CaCO3+2HCl=CaCl2+H2O+CO2, the reaction generates CO2, so the reaction between limestone and dilute hydrochloric acid will produce bubbles.

Limewater. and Bucket Dry.

Dilute hydrochloric acid. The reaction does not produce bubbles because.

ca(oh)2+

2hclcacl2

2H2O, reaction is generated.

water, the reaction phenomenon is not obvious, it should be limestone and dilute hydrochloric acid reaction, such as.

CaCO32HCl=CaCl2+H2O+CO2 reacts to form CO2, so the reaction between limestone and dilute hydrochloric acid will produce bubbles.

Potassium nitrate cannot react with round lime water or dilute hydrochloric acid.

It is a reaction with lime water with salt and alkali, and with hydrochloric acid is a reaction between salt and acid, and it does not meet the conditions of metathesis reaction (no water, gas, and precipitation), so it is not clear that the cavity reed reaction.
