Is khso4 a weak acid

Witryna29 sty 2024 · Anne Marie Helmenstine, Ph.D. Updated on January 29, 2024. A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid. WitrynaWhat are the concentrations of HSO4-, SO42-, and H+ in a 0.13 M KHSO4 solution? (Hint: H2SO4 is a strong acid; Ka for HSO4- = 1.3 10-2.) HSO4- _____M SO4^2 …
