Many bases are ionic compounds, but acids are not – they are molecular compounds. How do acids form ions in solution when they are not composed of ions? • Acids form ions as a result of their interaction with basicity of salt solutions by noting whether the corresponding acid and base are strong or weak. For example, NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt is acidic. Similarly, NaF is basic (it is the salt of a strong base, NaOH, and a weak acid, HF). NaCl is neutral. however, salts may be acidic, basic or neutral. An easy way to predict the acid–base properties of a salt is to consider the strengths of the “parent” acid and base that make up the salt. Let’s investigate the pH of salts dissolved in water.

basicity of salt solutions by noting whether the corresponding acid and base are strong or weak. For example, NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt is acidic. Similarly, NaF is basic (it is the salt of a strong base, NaOH, and a weak acid, HF). NaCl is neutral. In general, this is true. If you have the salt, this salt here that was formed from a weak acid and a strong base, these salts form basic solutions with pHs greater than seven. Let's look at one more example. This is the example of a strong acid and a weak base. HCl is our strong acid, and ammonia is our weak base. So HCl is H+ and Cl-. Is NH4Br an acid or base? Halides and alkaline metals dissociate and do not affect the H+ as the cation does not alter the H+ and the anion does not attract the H+ from water. The word "neutral" is sometimes added to "ammonium fluoride" to represent the neutral salt—[NH4]F vs. the "acid salt" (NH4HF2).

When working acid/base problems, keep an eye out for the strong acids and bases, but also for their conjugates, like I-, Cl-, Br-, ClO 4-, NO 3- and K +, Li +, Ca 2+, etc. Any combination of these anions and cations will produce neutral solutions. HSO 4-, the conjugate base of the strong acid, H 2 SO 4, is an exception. A solution of "ammonium perchlorate" would be slightly acidic in water. "Ammonium ion" is the conjugate acid of a weak base, "ammonia"; "perchlorate anion" is the conjugate base of a strong acid, HClO_4. And thus the acid base behaviour of the salt depends on the ammonium ion. Solution of ammonium perchlorate would be slightly acidic, and its pH governed by the equilibrium: NH_4^+ +H_2O(l ...3. Strong acids and strong bases are strong electrolytes [e.g., HCl(aq), H 2 SO 4 (aq), HClO 4 (aq); NaOH(aq)]. There are virtually no molecules of a strong acid or base in solution, only ions.
