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.


Why alkalis are sometimes describe as the opposite of acids?

Alkalis (bases) react with acids to neutralize them, so in one sense, they can be considered as "opposite" of acids. Bases produce pH values >7 and acids produce pH values <7.


What substance is made when alkalis react with oils and fats?

Soap


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 type of substance nutralises an acid?

An alkali substance typically neutralizes an acid. Alkalis are basic in nature and can react with acids to form salts and water, achieving a neutral pH.


Is AI an acid or base?

Aluminium is not an acid or a base, but it does react with both acids and alkalis.


Substance made when alkalis react with oils?

The process is called saponification, with which you make soap.


Do acids react with alkalis?

Yes, acids react with alkalis through a chemical reaction known as neutralization. During neutralization, an acid reacts with an alkali to form a salt and water. The acid donates a hydrogen ion (H+) and the alkali donates a hydroxide ion (OH-), resulting in the formation of water and a salt.


Is corrosive acid or alkali?

Both acid and alkali can be corrosive


How do you differentiate between an acid and an alkali?

An acid has a pH level below 7, whilst an alkali has a pH level above 7. Acids contain H+ ions and alkalis consist of OH- ions. Acids turn litmus paper red, alkalis turn it blue. When acids react with metals they form hydrogen and a salt. Acids a sour to taste. Alakalis react with acids to form salt and water, a reaction called neutralisation. Alkalies feel soapy to touch. All alkalis except ammonia will react with ammonium compounds, driving ammonia out.


Does copper react quickly with alkalis?
