Potassium is usually a spectator ion, and has no real effect in most solutions.
Carbonate ions, however, are a conjugate base of carbonic acid. Its properties, measured in terms of its acid dissociation constant, results in the formation of this acid. However, the protons which react must come from somewhere, and are thus removed frm the solution. This lowers the concentration of hydronium and therefore the pH increases, making it (more) basic (than it was before).
The H+ and OH- ions combine to form water.
When an acid solution is mixed with a basic solution, there will be a neutralization reaction in which hydrogen ions from the acid will combine with hydroxide ions from the base, to form water.
No, it will form a basic solution of Sodium Hydroxide as per the following equation. Na2O + H2O ---> 2NaOH As the solution will have OH- ions so it will be basic. Na2O is a basic oxide and basic oxide dissolve in water to form bases( here NaOH). Acidic oxides dissolves in water to form acids. Alkali metal(group 1 of periodic table) oxides are always basic oxides, but all metal oxides may not be basic( some transition metal oxides are acidic).
I believe it should be a basic solution... When you have metals with a weak acid's anion, you receive basic solution in water.... HClO2, chlorous Acid, is a weak acid. The Potassium, K an alkali metal, is now where the H+ was, making it KClO2 and that acts as a base in water
what volum of 0.55M Ni(NO3)2, will react with 85ml of 0.25m K2CO3, to form NiCO3 ?
The water solution is neutral.
Yes.
The H+ and OH- ions combine to form water.
The solution formed will be basic in nature. This is because of the formation of NH(4)OH which is alkaline.

No, it forms a basic solution containing ammonium hydroxide.
Salts can create acidic or basic solutions by containing a conjugate base and a weak acid, which when dropped in a solution of water reacts with the water to form a solution with a pH greater than seven.

MgO + H2O -> Mg(OH)2 Basic. Magnesium hydroxide is the usual product here.

it forms metal hydroxidesIt gets poisoned
