Answers
Answer:
Acid :- acid, any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).
Explanation:
Base :- A base is a substance that reacts with an acid in an acid-base reaction. ... Generally, a base either accepts a proton, releases a hydroxide anion when dissolved in water, or donates an electron. Examples of bases include hydroxides and soap. Salt :- In chemistry, a salt is any neutral chemical compound made of cations (positive ions) attached to anions (negative ions). The main kind of salt is sodium chloride with the chemical formula NaCl. Chemical :- A chemical by definition is any substance consisting of matter; this includes solids, liquids, and gas. Chemicals can either be of a pure substance or a mixture of substances. A chemical substance such as water (H2O) is a pure chemical because it has the same molecules and combination throughout its structure
