The answer is Na⁺.
Na⁺ is a positive ion of sodium that is due by the loss of one electron.
4He represents four atoms of helium. It is an idel gas, that do not form elementary molecules and exist in atom form.
Ca represent one atom of calcium and Mg one atom of magnesium. They are metals and do not form elementary molecules.
pH = - log[acid] = -log [H+]
pH= -log[10] = 1
Thus, pH is 1
if pH is 7, the solution is neutral and if pH is greater than 7 the solution is basic and if it is less than 7 the solution is acidic.
This solution have pH = 1, thus the solution is acidic.
When an atom or molecule loses an electron it is oxidized and the reaction is called oxidation, when an atom or molecule gains an electron it is reduced and this is known as reduction. Both oxidation and reduction are known as Redox reaction
