which metal reacts with alkali to produce hydrogen?
sodium hydroxide
ammonium chloride appears to sublime upon heating but actually decomposes into ammonia and hydrogen chloride gas.









































ammonium chloride reacts with a strong base, like sodium hydroxide, to release ammonia gas:









































similarly, ammonium chloride also reacts with alkali metal carbonates at elevated temperatures, giving ammonia and alkali metal chloride:









































a 5% by weight solution of ammonium chloride in water has a ph in the range 4.6 to 6.0.









































some of ammonium chloride's reactions with other chemicals are endothermic like its reaction with barium hydroxide and its dissolving in water.

all the alkali metals react vigorously or explosively with cold water, producing an aqueous solution of a strongly basic alkali metal hydroxide and releasing hydrogen gas. this reaction becomes more vigorous going down the group: lithium reacts steadily with effervescence, but sodium and potassium can ignite and rubidium and caesium sink in water and generate hydrogen gas so rapidly that shock waves form in the water that may shatter glass containers. when an alkali metal is dropped into water, it produces an explosion, of which there are two separate stages. the metal reacts with the water first, breaking the hydrogen bonds in the water and producing hydrogen gas; this takes place faster for the more reactive heavier alkali metals. second, the heat generated by the first part of the reaction often ignites the hydrogen gas, causing it to burn explosively into the surrounding air. this secondary hydrogen gas explosion produces the visible flame above the bowl of water, lake or other body of water, not the initial reaction of the metal with water (which tends to happen mostly under water). the alkali metal hydroxides are the most basic known hydroxides.
