A hydronium ion is formed when a positively charged hydrogen ion bonds with a molecule of water through a coordinate covalent bond.
What is the hydronium ion concentration in a solution where the hydroxide ionconcentration is 1 x 10-9 M? 3O+] and is the unknown quantity. The hydroxide ion concentration is represented by [OH-] and is 1 x 10-9 M. So the final hydronium ion concentration is 1 x 10 -5M. Comparison of 1 x 10 M versus 1 x 10-9 M. 3O+] > [OH-] so the solution is acidic.
