Question

what is called Acids . How we can find it test in any object​

Answer 1

Answer:

An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons.

Add one tablespoon (15 ml) of cabbage juice to each of two cups. Describe the color of the juice.Keep one of the cups as a control (don't add anything to it). To the other cup, add a few drops of liquid acid or base or about one-eighth teaspoon of solid acid or base.Swirl to mix the test solution and acid or base. Immediately observe the color and describe it. (The solutions will be in the red range with added acid, and in the green to blue range with added base. The colors in base are particularly "fragile" and change from one hue to another in a few minutes.)

Answer 2

An acid is a molecule or ion capable of donating a proton (hydrogen ion H+) (a Brønsted–Lowry acid), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid). ... A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution.

test for acid: take a blue litmus paper and drop the acid with a dropper the paper will turn blue to red
