Write the ions present in solution of k2co3. express your answers as chemical formulas separated by a comma. identify all of the phases in your answers.

Answer : The ions present in the solution of are and in aqueous state.

Explanation :

When is in aqueous solution then they dissociates into their ions.

The reaction in aqueous medium is,

The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.

Therefore, the ions present in solution of are and [tex]CO^{2-}_3[tex] in aqueous state.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
