What else can I help you with?
Do alkalis react with metals?
Yes, alkalis can react with metals to form metal hydroxides and hydrogen gas. The reaction typically involves the alkali breaking down the metal's oxide layer to generate hydrogen gas and a metal hydroxide.
How does copper nitrate react with copper oxide?
It doesn't.
How can alkalis remove grease and oil?
Alkali react with greases and oils forming water soluble soaps.
What happes when you react copper with oxygen?
It forms copper oxide
Does alum react with cooper?
Yes, alum (potassium aluminum sulfate) can react with copper to form aluminum oxide and copper sulfate. This reaction is often observed in processes such as etching or electroplating of copper.
Do acids react with alkalis in a combustion reaction?
No, acids and alkalis do not react in a combustion reaction. Combustion reactions involve a substance reacting with oxygen to produce heat and light. Acids and alkalis typically do not react in this way.
Does acids react with alkalis in a combustion reaction?
No, acids and alkalis do not react in a combustion reaction. Combustion is a chemical reaction that involves a substance combining with oxygen to produce heat and light. Acids and alkalis react in neutralization reactions, where they form water and a salt.
What substance is made when alkalis react with oils and fats?
Soap
Do alkalis react with metals?
Yes, alkalis can react with metals to form metal hydroxides and hydrogen gas. The reaction typically involves the alkali breaking down the metal's oxide layer to generate hydrogen gas and a metal hydroxide.
What does alkali plus metal give?
Alkalis and metals do not usually react.
What is made when acids react with alkalis?
When acids react with alkalis, they undergo a neutralization reaction to form salt and water. This process involves the transfer of protons from the acid to the alkali, resulting in the formation of a salt and water as the products.
What happens to the alkalis when they react with ammonium salts?
When alkalis react with ammonium salts, they form ammonia gas, water, and the corresponding salt. This reaction is known as an acid-base reaction, where the alkali acts as the base and the ammonium ion acts as an acid. The ammonia gas is released as a byproduct of the reaction.
Does copper react with nitrogen?
Copper does not react with nitrogen under normal conditions. However, at very high temperatures and pressures, copper can react with nitrogen to form copper nitride.
Is AI an acid or base?
Aluminium is not an acid or a base, but it does react with both acids and alkalis.
How reactive is copper?
Copper does not react in water.
What are the hazards in alkalis?
Hazards of alkalis include skin and eye irritation upon contact, potential respiratory irritation if inhaled, and risk of burns or corrosion if ingested. Alkalis are also caustic and can react dangerously with other substances if not handled properly.
Why does rubbing an alkaline on to a bee sting work?
because the bee sting has acid and alkalis react
