Because the reaction is highly exothermic. when potassium touches water the substances react chemically and the bonds created, thereby releasing a lot of energy. This energy can ignite the hydrogen gas produced to create flames.
Potassium reacts vigorously with water to produce potassium hydroxide and hydrogen gas. This reaction releases a lot of heat and hydrogen gas, which can ignite, resulting in a flame or explosion. Therefore, it is not safe to put potassium in water.
Potassium reacts with water to produce potassium hydroxide (KOH) and hydrogen gas (H2).
Potassium produces potassium hydroxide when reacted with water. It can also form various salts, such as potassium chloride, potassium nitrate, and potassium sulfate, when combined with other elements or compounds.
Sodium hydroxide (NaOH) react with dilute Hydrochloric Acid (HCl) to form Sodium chloride (NaCl) and water (H2O).
Water is formed by the combination of H+ ions from sulfuric acid and OH- ions from potassium hydroxide to produce H2O molecules. This reaction is a typical acid-base neutralization reaction where the acid and base react to form water and a salt.
To test for strontium nitrate, you can perform a flame test which will produce a red flame color. For ammonium carbonate, it will release ammonia gas when heated and form a white precipitate when reacted with a sodium hydroxide solution. Potassium sulfate can be identified by its solubility in water, as it is highly soluble.
When potassium metal reacts with water, it produces a lilac-colored flame. This flame color is a result of the energy released during the chemical reaction between potassium and water.
Potassium has a violet color in the flame test.

When aqueous potassium hydroxide is reacted with sulfur dioxide, potassium sulfite (K2SO3) and water are produced. The balanced chemical equation for the reaction is: 2KOH + SO2 → K2SO3 + H2O.
Potassium metal does not change color when mixed with water. However, it reacts vigorously with water, producing hydrogen gas and forming potassium hydroxide. The reaction is exothermic, releasing a significant amount of heat. This reaction is often used to demonstrate the reactivity of alkali metals with water.
water, carbon dioxide and a salt
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.
