In chemistry and physics, the atomic number<span> of a chemical </span>element<span> (also </span>known<span> as its </span>proton number<span>) is </span>the number of protons<span> found in the nucleus of an </span>atom<span> of that </span>element<span>, and therefore identical to the charge </span>number<span> of the nucleus. It is conventionally represented by the symbol Z.</span>
pH ranges depending on the solution, for a solution with weak acid pH will be between 4.0-7.0.
<h3>What is pH?</h3>
pH is helps to determine if a solution is acidic or basic in nature.
A pH meter is the instrument that can be used for the measurements.
Methyl orange is used when titrating a strong acid against a weak base.
Therefore, the pH of the solution which is a weak acid will be between 4.0-7.0.

The answer is reduction reaction. For every oxidation reaction that takes place, a reduction reaction must also happen, no reduction can occur without oxidation and vice versa. In redox reaction, atoms or ions undergo changes in the electronic structure, involving the transfer of electrons between reactants.
