Phosphoric acid is a weak oxyacid with three replaceable hydrogen atoms. Its pKa value is 2.14. It donates its acidic hydrogen in an aqueous solution to form its conjugate base, H2PO4-. Is H3PO4 a strong or weak acid? It follows three sequential deprotonation steps to release all three ...
Why does a strong acid have a weak conjugate base? Give an example of a conjugate pair in which neither species is either a strong acid or base. (Identify the acid and the base.) What is the best way to identify conjugate acids and conjugate bases? Which of the following acids will ha...
An acid dissociates into protons and anions in the aqueous solution and reacts with a base to form salt and water. A strong acid almost entirely ionizes in the aqueous solution whereas a weak acid fractionally ionizes in the aqueous solution. Generally, an acid reacts with metals ...
a) NH_3, strong acid b) NaOH, strong base c) HCl, weak acid d) H_2CO_3, strong acid e) Ca(OH)_2, weak base Is H2CO3 a strong or weak acid? Explain. Which of the following are strong acids? Which are weak acids? a. HC_2H_3O_2. b. HCl...
The highest pH refers to a low concentration of hydronium or hydrogen ions. This means acids have low pH values and alkalies (bases) have high pH. Answer and Explanation: Salts : These are formed using an acid and a base of different strengths: strong ...
The ion-exchange capacity of the CJMA-2m membrane do not differ significantly from those of the CJMA-2 because the acid–base method (see Supplementary Materials) is applied to determine them. This method takes into account both strong basic and weak basic fixed groups of the CJMA-2 membran...
