Question

what is acid?????????
​

Answer 1

Answer:

An acid is a substance that can donate one or more of its hydrogen ions to another substance.

Explanation:

Strong acids let go of many or all of their ions. Weak acids hold onto some of their ions. The opposite of an acid is a base. Acids taste sour and can burn things like skin and even metal.

thanks, have a nice day! also mark me brainliest pls.

Answer 2

• A Brnsted–Lowry acid or a Lewis acid is a molecule or ion capable of donating a proton (i.e., hydrogen ion, H+) or creating a covalent bond with an electron pair.
• Proton donors, sometimes called Brnsted–Lowry acids, are the first group of acids.
• Proton donors, which create the hydronium ion H3O+ in aqueous solutions, are referred to as Arrhenius acids.
• The Arrhenius hypothesis was expanded to include non-aqueous solvents by Brnsted and Lowry.
• A hydrogen atom attached to a chemical structure that is still energetically advantageous after loss of H+ is commonly found in a Brnsted or Arrhenius acid.
