Answer 1

Answer:

Acids and Bases play an important role in chemistry. We see them everywhere in our day to day lives, from our cleaning agents; soaps and detergents, to baking soda. Acids and bases (alkaline earth metal chemical element) are 2 categories of corrosive substances. Any compound with a pH value between zero to seven is considered acidic, whereas a pH value between seven to fourteen is a base. An acid is called a proton donor, while a base is called a proton acceptor (Kolb, 1978).

$\sf{\underline{\overline{\pink{Acids}}}}$

• Acids are defined as compounds which contain one or more hyrdogen atoms and when dissolved in water, produce hydronium ions (H3O+) the only positively charged ions.

• They are sour to taste

• Some of them are solid and some are liquids at room temperature.

• All mineral acids have corrosive action on the skin and cause painful burns.

• They change the colour of indicators. (Litmus-Blue to red, Methyl orange-Orange to pink, Phenolphthalein-Remains colourless)

$\sf{\underline{\overline{\red{ Bases}}}}$

• Base is either a metallic oxide or a metallic hydroxide or ammonium hydroxide which reacts with hydronium ions of an acid to form salt and water only.
• They are bitter to taste.

• They are soapy substances i.e they are slippery to touch.

• They show a mild corrosive action on the skin(slight burn).

• They change the colour of indicators. (Litmus-Red to Blue, Methyl orange-Orange to yellow, Phenolphthalein-Colourless to pink).
