Difference in Concentrations

Postby Jedrick Zablan 3L » Sun Dec 01, 2019 7:17 pm

Why do acids have a higher H30+ concentration and why do bases have a higher OH- concentration?

Acids release H+ ions in water, while bases release OH- ions in water.

the concentrations of hydronium and hydroxide are characteristics of acids and bases. Since acids donate a proton (H ion), that proton reacts with water, forming hydronium. Thus, when an acid reacts with water, there is a higher concentration of hydronium. Similar for bases, except with hydroxide. Bases accept protons. Often water donates this proton, thus H2O becomes just OH after donating its proton.

The definition of an acid and base lies in the relative concentrations and characteristics associated with hydronium ion and hydroxide ions. Acids donate protons (H ions), while bases accept these (donate OH-). This can be seen in the basic formula for acid/base reaction:
HA (parent acid) + B (parent base) -> A- (conjugate base) + BH (conjugate acid)
