The same is true for a weak base + strong acid, at the equivalence point 100% will be converted into the conjugate acid, a weak acid, can react with water to produce H + so the pH will be less than 7 2 Reply ghowtte • 2 yr. ago Thanks! siaya county integrated development plan

"Web25 okt. 2024 · Acids that partially dissociate are weak acids, while acids that fully dissociate are strong acids. Explanation: The pH scale range from 0 to 14. A pH of 7 is neutral; below it is acidic while a pH above 7 is basic. While low pH might be an indication of a strong acid, a high pH on the pH scale indicates a base or alkaline.

Explain Yes, … WebA strong acid is said to completely ionize in water whereas a weak acid is said to only ionise partially. As there are different degrees of ionization of acids, there are also different levels of weakness for which there is a …

WebWhen a weak base and a strong acid are mixed, they react according to the following net-ionic equation: B (aq) + H₃O⁺ (aq) → HB⁺ (aq) + H₂O (l). If the acid and base are equimolar, the pH of the resulting solution can be determined by considering the … Web23 jun. 2011 · The strength of an acid is its ability to ionize or donate the hydrogen ion in an aqueous solution reacting with water.

WebAn acid which is strong in water may be weak in a less basic solvent, and an acid which is weak in water may be strong in a more basic solvent. According to Brønsted–Lowry acid–base theory, the solvent S can accept a proton. For example, hydrochloric acid is a weak acid in solution in pure acetic acid, , which is more acidic than water.
