Ph of strong acid and weak acid

WebFeb 25, 2024 · The question is to find out the p H of a mixture of weak acid and strong acid. My book just states the formula as p H = − log C 2 + C 2 2 + 4 K a C 1 2 where C 1 is the … WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. …

What actually happens in strong acid- weak base reactions?

WebThe pH scale measures a solution’s acidity or alkalinity. The range for the pH scale is 0 (strong acid) to 14 (strong alkali). pH 0 – 2: strong acid pH 3 – 6: weak acid pH... WebJan 31, 2024 · This derives from the general formulas for both pH and a new quantity, pKa. pH = − log[H3O +] = − log(10 − 7) = 7 pKa = − logKa = − log(10 − 14) = 14 Note Some texts incorrectly use 15.7 for the pKa of water. Here is a link to an explanation of why 14 is better. software ezmeral https://amgoman.com

Choose 1 answer: Weak acid A Weak … WebMay 30, 2024 · The strategy of major species You correctly describe the strategy. First, let reactions go to completion (in the direction that makes sense, i.e. weak base and strong acid forms weak acid and spectator ion - never the other way around). Then, check what the major species are and estimate the pH. WebThe difference between the two is that muriatic acid is a strong acid and vinegar is a weak acid. Muriatic acid is strong because it is very good at transferring an H + ion to a water molecule. In a 6 M solution of hydrochloric acid, 99.996% of the HCl molecules react with water to form H 3 O + and Cl-ions. software ezp2010
