Answers
Answer:
5a.Mineral acids : A mineral acid is an acid derived from one or more inorganic compounds. All mineral acids form hydrogen ions and the conjugate base when dissolved in water. A mineral acid or inorganic acid is any acid derived from an inorganic compound that dissociates to produce hydrogen ions (H+) in water. Mineral acids are highly soluble in water but tend to be insoluble in organic solvents. The inorganic acids are corrosive.
b. Alkali : In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0.
c. Natural Acids : An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO₂OH, are relatively stronger acids. Fluoroantimonic acid
The strongest acid on record is fluoroantimonic acid – it's known as a superacid, meaning it has an acidity greater than completely pure sulphuric acid.
d. Antacids : An antacid is a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion or an upset stomach. Antacids are a class of medicines that neutralize acid in the stomach. They contain ingredients such as aluminum, calcium, magnesium, or sodium bicarbonate which act as bases (alkalis) to counteract stomach acid and make its pH more neutral.
