k2co3 major species present when dissolved in water

Answers

When K2CO3 is dissolved in H2O (water) it will dissociate (dissolve) into K+ and CO3 2- ions. To show that they are dissolved in water we can write (aq) after each. The (aq) shows that they are aqueous – dissolved in water.

The major species present in the solution when K₂CO₃ dissolved in water are K⁺, CO₃²⁻ , and HCO₃⁻.

What is the interaction between salt and water?

When salt is added to water, the salt dissolves because the ionic bonds in the salt molecules are weaker than the covalent bonds of water. The salt dissolves in water at the molecular level due to electrical charges. Due to the fact that both salt and water are polar.

The bonds in salt are ionic bonds and to dissolve the salt, the positively-charged side of the water is attracted to the negatively-charged ions of salt and the negatively-charged side of the water is attracted to the positively-charged ions of salt.

The dissociation of the potassium carbonate in water:

K₂CO₃ (aq)  →  2K⁺ (aq)  +  CO₃²⁻ (aq)

H₂O (l) →   H⁺ (aq) + OH⁻ (aq)

Carbonate ions are combined with hydrogen ions from water:

CO₃²⁻ (aq) +  H⁺  (aq)  ⇆  HCO₃⁻  (aq)

Therefore, K⁺, CO₃²⁻ , and HCO₃⁻ ions are present when K₂CO₃ dissolved in water.
