Question

state different between acid and bases​

Answer 1

Answer:

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).

$\sf{\underline{\overline{\pink{Acids}}}} </p><p>$

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).
