Question

what is bace, acid and salt​

Answer 1

Base are substances that, in aqueous solution, release hydroxide (OH−) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue)

Acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair.

Salt is a chemical compound consisting of an ionic assembly of cations and anions. Salts are composed of related numbers of cations and anions so that the product is electrically neutral.

Step-by-step explanation:

Properties of Acids, Bases and Salts

Acids, bases and salts affect chemistry as well as our day to day life. They can be easily identified by their taste; that is acids taste sour and bases taste bitter and salts itself have salty taste.

Properties of acids

• Acid is a compound which yields hydrogen ion (H+)(H+), when dissolved in water.

HCl+H2O→H++Cl−HCl+H2O→H++Cl−

• Acid is sour to the taste and it is corrosive in nature. The pH of acids is less than 7.

• All acids react with metal to release hydrogen gas. For example, zinc metal reacts with hydrochloric acid to form zinc chloride and hydrogen gas.

Zn+2HCl→ZnCl2+H2Zn+2HCl→ZnCl2+H2

• When acids react with limestone (CaCO3), it produces carbon dioxide. For example, HClHCl reacts with limestone to produce carbonic acid and calcium chloride.

CaCO3+2HCl→CaCl2+CO2+H2OCaCO3+2HCl→CaCl2+CO2+H2O

• Acids are classified into organic and inorganic acids. The best example of organic acid is acetic acid (CH3COOH)(CH3COOH), and inorganic acids are those which are produced from minerals; for example, sulphuric acid (H2SO4)(H2SO4), and hydrochloric acid , etc.

• Acid usually converts blue litmus paper to red litmus paper.

• Acids have a tendency to quickly corrode the metal surfaces.

Properties of bases:

• Bases are compounds which yields hydroxide ion (OH−)(OH−), when it is dissolved in water.

• Bases are bitter in taste and are corrosive in nature. They usually feel slippery and very soapy.

• Bases are good conductor of electricity and usually shows a pH value of more than 7.

• Bases react with oils and grease to form molecules of soap.

• Bases convert red litmus paper to blue litmus paper.

• Bases also have the tendency to corrode the surface of metals.

Properties of salts:

And salts are also known as neutral which means neither acid nor base it's normal.
