Answer :

How many molecules of mno4- ions were involved in the reaction when oxalic acid solution was provided? Oxalic acid had completely been consumed when KMnO4 is supplied, and the emergence of a pink colour indicates the reaction's end point, which is caused either by introduction of a small excess of KMnO4. As an ego, KMnO4 is used.

An ion is an atom or collection of atoms where the number of electrons and the number of protons are different. A positive ion, also known as a cation, is a particle that occurs when the amount of electrons exceeds the number of protons. Ions are electrically charged particles that can be produced either by taking electrons away from neutral atoms to produce positive ions or adding electrons to neutral atoms to produce negatively charged ions.
