Question

How does the solubility of CO2 in water vary with:

A. an increase in pressure of CO2 (g)? Explain your answer.

B. an increase in water temperature? Explain your answer.

C. a decrease in water temperature? Explain your answer.

Answer 1

Solubility of co₂ in water is increases with increase pressure In of CO2, because of when CO2 reacts increase lasing with water It forms Carbonic Acid (H2003) the reaction dewible the Pressure of CO₂ it makes of co2 in the forward reaulton and hence solubilety 2ncreases with mcrease Decreasy re. Because of Solubilety of co₂ in water is the temparatur Prereases the temparature that overcomes to the solution Energy the attractive forces between and the solvent gas molecules, there by decreasing the solubilety of gay.co.z. provides thermal Ener the b. Increases c) solubility of CO₂ in water is at low en temperature, because of with Decrears water temparatures the coa gas ir interact with molecules to form H₂CO3 most of ca, gas is Dissole in water. It is an Exothermic process D AH <O = Temparatuse Decreaseso soin solubilety of coa gas a pressure a Temparature
