H2+1 + S-2 = H2S (Hydrogen Sulfide)
H2+1 + 2OH-1 = 2H2O (Water)

The equation for calculating H+ concentration is pH = -log[H+], where [H+] represents the concentration of hydrogen ions. For OH- concentration, pOH = -log[OH-]. These equations are used to quantify the acidity or alkalinity of a solution.
The equation for the dissociation of water is: H2O ↔ H+ + OH-
The chemical equation is:Na + OH- + H+ + Cl- = Na+ + Cl- + H2O(l)
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
When acids dissolve in water they release a proton - also called a H+ ion. So the answer is "a". The level of acidity is due to H+ and level of alkalinity due to (OH)-. This is displayed in the equation pH=-log[H+] i.e. concentration of H+ ion.
The equation is: H2O------>H+ + OH-
