Question: is kclo4 an acid or base?
Answer: (b) Potassium perchlorate, KClO4, is a neutral salt. Neither K+ nor ClO4- has any tendency to donate or accept a proton in dilute aqueous solutions. The reaction between a strong base KOH and the strong acid HClO4 produces KClO4. (c) Potassium hydrogen sulfate (also called potassium bisulfate) is an acidic salt.
