Such substances are semi-metals as Zn,Sn and Al , and their oxides, such substances are known as Amphoteric.
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.
The process is called saponification, with which you make soap.
Nitric acid reacts strongly with many metals.
Not that many. It is wonderfully resistant to most stuff, including oxidation in air. That's why it's a good choice for making jewelry. It can be corroded by caustic alkalis, cyanides, halogens and sulfur, and it is soluble in aqua regia. Platinum can act as a catalyst in a number of situations. The most popular one is as the active element in automobile catalytic converters. Wikipedia has additional information, and a link is provided.
Metallic magnesium reacts violently with acids.
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.
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.
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.
Soap
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.
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.
Aluminium is not an acid or a base, but it does react with both acids and alkalis.
The process is called saponification, with which you make soap.
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.
Both acid and alkali can be corrosive
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.
Copper doesn't react wih alkalis.
