Question

above what concentration of hydronium ions in h30+ ,is an aqueous solution considered to be acidic at 25°c?explain

Answer 1

A solution is said to be acidic if it contains a higher concentration of hydronium ions $[H_3O^+]$ than hydroxide ions. A neutral solution has a pH of 7. At $25°$C an acidic solution have less concentration of hydroxide ion molarities and a higher concentration of hydronium ions molarities i.e( a pH of less than 7 and a pOH greater than 7)
