When hydronium ions increase than OH- ions also increase. Is this true?

Solution

Hydronium ion can be formed when an acid is present in water. It's chemical formula is H 3 O + . It can also be formed by the combination of a H⁺ ion with an H2O molecule.
It decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules. Hence the hydronium ions (H3O+) decreases with the increase of OH- ions.

_________ increases with the increase in OH^- ions.

When we increase the acid volume in water, $H^{+}$ or ${O H}^{-}$ ions are released, then :

Q. In III group precipitation

N H_{4} C l

is added before adding

N H_{4} O H

Assertion: when NaOH is added to the HCl solution, the conductance of the solution decreases right upto the equivalence point and then increases.
Reason: At starting, fast moving to ions replaced by relatively slower moving $N a^{\oplus}$ ions and after the equivalence point, as $O H^{-}$ start increases conductance increases.
