WebComparing the values of K a for the acidic cation and K b for the basic anion, we determine the solution will be acidic because K a > K b. When K a ≈ K b, a Neutral Solution is Formed. One more possibility is when the salt of a weak acid and weak base produces a neutral solution. This is somewhat similar to what we saw for salts containing ... WebDec 5, 2015 · Long story short, the ultimate cause of non-neutral pH in the solutions of some salts is hydrolysis.If a salt is made from a weak acid and strong base, then the acid anion would get partially protonated by water, like $\ce{CH3COO- + H2O <=> CH3COOH + OH-}$, and that $\ce{OH-}$ would be responsible for the overall alkaline pH of the resulting …

WebStep 1: Read through the given information, and determine if the salt comes from a weak acid or weak base. The salt comes from KOH K O H, a strong base, and HClO4 H C l O 4, … WebIf it is prepared from a strong base and weak aid, the solution will be basic, and if it is a combination of a strong acid and a strong base, a neutral solution will be formed.

pH of a Salt Solution - Chemistry Steps
WebNov 4, 2024 · The pH of the solution formed by the reaction of a weak acid with a weak base depends on the relative strengths of the reactants. For example, if the acid HClO has a K a of 3.4 x 10 -8 and the base NH 3 has a K b = 1.6 x 10 -5 , then the aqueous solution of HClO and NH 3 will be basic because the K a of HClO is less than the K a of NH 3 . WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. WebSep 5, 2015 · Sodium sulfate is a neutral salt: its aqueous solutions exhibit a pH of 7. The neutrality of such solutions reflects the fact that sulfate is derived, formally, from the strong acid sulfuric acid. Furthermore, the Na+ ion, with only a single positive charge, only weakly polarizes its water ligands provided there are metal ions in solution. deweys tire service platteville wi
