What reactions occur when...?

Two chemical reactions occur:
Potassium metal undergoes oxidation with water to give hydrogen gas, and potassium hydroxide. Potassium chloride in aqueous solution forms aquated potassium and chloride ions, which do not affect the concentrations of
Potassium hydroxide is commonly used as a cleaning agent, as an electrolyte in batteries, and (so the internet tells me!) used to remove the horns on calves (ouch!).
