Is CH3NH3 an acid? C2H3O2 on the other can accept a proton so C2H3O2 is a base but its a conjugate base to acid HC2H3O2 since it is generatd by losing a proton from HC2H3O2 . It is because barium bromide reacts promptly with air. The reaction between a strong base KOH and the strong acid HClO4 produces KClO4. The pH does not decrease drastically because the HCl reacts with the _____ present in the buffer solution. split the salts into their respective cations and anions and see which ones are strong and which ones are weak.
