In case you did not know, the part of the salt from the weak acid removes some of the H+ ions from the water equilibrium causing changes in this equilibrium that result in [OH-] increasing. Do feel, Great list! Who is Jason crabb mother and where is she? Predict whether aqueous solution of each of the following salts is acidic, basic, or neutral? $$\begin{align} When it is dissolved in an aqueous solution, it accepts the H + ion from a water molecule and produces hydroxide ions (OH ) that correspondingly shows, its basic nature. The protonated species B+H is now an acid, and it is called the conjugate acid of base B:. This problem has been solved! Being part of the list of strong acids doesnt give any indication of how dangerous or damaging an acid is though. How do you determine if a molecule is an acid or a base? For CH3NH3Cl, we know that Cl- is the conjugate base of HCl (a strong acid), which means that Cl- has no affect on the pH.
