Answer: If the oxidation number of copper changes from 0 to +2 then yes this is a redox reaction as copper lost 2 electrons and was oxidized.

Explanation:

When an element or atoms loses an electron then it acquires a positive charge.

This charge on an atom represents its oxidation state.

For example, 2AgNO_{3}(aq) + Cu(s) \rightarrow Cu(NO_{3})_{2}(aq) + 2Ag(s)

Here, oxidation number of copper changes from 0 to +2.

A redox reaction in which electrons are removed from an atom or a reaction where an increase in oxidation number of an atom takes place is called oxidation-half reaction. The atom itself gets oxidized.

This means that here copper lost 2 electrons and was oxidized.

Thus, we can conclude that if the oxidation number of copper changes from 0 to +2 then yes this is a redox reaction as copper lost 2 electrons and was oxidized.

Acidity is a measure of the amount of dissolved hydroxide ions in a solution.
Gekata [30.6K]

The concentration of hydrogen ions in a solution is a measure of its acidity. So the correct option is (b) false.

When an Arrhenius acid is dissolved in water, hydrogen ions are produced:

H+(aq) + A- = HA + H2O (aq)

Here, H+ is the hydrogen cation, A- is the solvated anion, also known as the conjugate base, and HA is the non-dissociated acid. When an Arrhenius base is dissolved in water, hydroxide ions are produced:

BOH + H2O → B+(aq) + OH-(aq)

Is a material with at least one hydrogen atom that has the ability to split apart in an aqueous solution to produce an anion and an H + ion (a proton), creating an acidic solution. Bases are substances that, when dissolved in water, create hydroxide ions (OH) and a cation, resulting in a basic solution.
