A strong electrolyte dissociates completely into ions in aqueous solution. When potassium nitrite, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.
KNO2(s) K+(aq) + NO2-(aq)
We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
I guess it would eventually go to the hydroxide and emit CO2. I am not sure of the temperature needed
Once potassium bicarbonate reaches a temperature of about 100 to 120 degrees Celsius it undergoes a decomposition reaction: 2(KHCO3) = K2CO3 + H2O + CO2. This is a chemical change.
When sufficiently heated, potassium carbonate decomposes to potassium oxide and carbon dioxide gas according the equation K2CO3 -> K2O + CO2.
It gives off potassium carbonate, water and carbon dioxide
A strong electrolyte dissociates completely into ions in aqueous solution. When potassium acetate, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves by the following equation:KCH3COO(s) ----> K+(aq) + CH3CO2-(aq)
The reaction equation is: 2K + Cl2 --> 2KCl

They react pretty violently with water. These elements have 1 valence electron with makes them very reactive. When they are put in the water they split the water molecule into Hydrogen gas and NaOH or LiOH, etc. Lithium, sodium and potassium while violent reactions are pretty mellow compared to the reactions of Rubidium, Cesium and Francium. Search google video for cesium reaction with water and you will see what i mean.
Co2+ + 2SO4
Write the reaction when potassium sulfide is put into water:
A water solution is obtained.
Potassium metal will react violently with water to form KOH and hydrogen gas. Due to the heat released by the reaction - the hydrogen gas will ignite. So: placing potassium in water will cause a fire!
Potassium reacts violently with water to form POTASSIUM HYDROXIDE(KOH)and hydrogen gas K+H2O---------- KOH+H2 The H2 catches fire due to the heat of the reaction which in turn ignites potassium .potassium burn's with a crimson flame.
the formula of potassium carbonate is k2co3 because the valency of potassium (k1+) valency of carbonate is (co32-) interchange the valencies and don't put the signs then it will become (k2co3) so the formulae of potassium carbonate is k2co3
The potassium reacts with the water to form potassium hydroxide and hydrogen gas. The reaction is very exothermic, and the hydrogen explodes during the reaction. THIS IS A VERY DANGEROUS REACTION! DO NOT ATTEMPT IT ON YOUR OWN!
A strong electrolyte dissociates completely into ions in aqueous solution. When potassium acetate, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves by the following equation:KCH3COO(s) ----> K+(aq) + CH3CO2-(aq)
Potassium metal is a metal that explodes when put in cold water. It causes a chemical reaction which results in a large explosion.
Pure Potassium (K) will catch fire and may explode upon contact with water or very humid air.
The potassium catches on fire and then explodes. Seriously. Don't try it.
The reaction equation is: 2K + Cl2 --> 2KCl
Solid. Not to be put in water (But fun) :)
