Question

1. Why toothpastes have mild bases?

2. Why are carbonic acids and acetic acids are mineral acids but they are present in food stuff?​

Answer 1

Answer:

1) In simple terms, some toothpastes (not all) use very mild bases to help combat acid residue left by bacteria in the mouth. ... The toothpaste combats this acidity with a mild base. When an acid and a base reacts, you get water and salt. These are essentially pH neutral and cause no harm to the teeth.

2) Carbonic acid is considered an inorganic acid because of the structure of the molecule. Usually organic compounds contains carbons and hydrogens but at least one hydrogen is bonded to a carbon. For carbonic acid, none of the hydrogen bonds to the central carbon thus carbonic acid is an inorganic compound.

hope it helps ☺️

Answer 2

Answer:

1. Because acid forming bacterias produces acid in our mouth which can corrode the calcium phosphate salt of tooth enamel hence to neutralize the acid toothpastes are mild bases.

2. Because carbonic acid and acetic acid are mild acids as the acids are sour in taste they are used to increase the taste of food.
