Back

NaOH can convert ammonium salts into ammonia gas and water.

Front

What is the action of alkalis (NaOH, KOH) on certain metals?

Back

Alkalis can react with certain metals to produce hydrogen gas and metal hydroxides.

Front

What is the action of alkalis on metal oxides and hydroxides?

Back

Alkalis can react with metal oxides and hydroxides to form soluble metal alkoxides or hydroxides.

Front

What is the action of alkalis on organic compounds?

Back

Alkalis can hydrolyze certain organic compounds, leading to the formation of alcohols and other products.

Front

What happens when alkalis react with acids?

Back

Alkalis neutralize acids to form salt and water in a reaction known as neutralization.

Front

What is the effect of NaOH on phenols?

Back

NaOH can deprotonate phenols, resulting in the formation of phenoxide ions.
