Ph of an aqueous solution of cahpo4
WebConcept: (i) A buffer is an aqueous solution designed to care a constant pH, uniform whenever exposes to minor amounts of acids or bases. (ii) Whether acidity (pH < 7) or basic (pH > 7), a buffer solution consists of a weak acid or base mixed with the salt of its conjugated base or liquid, respectively. WebThe \text {pH} pH for an aqueous solution is calculated from [\text {H}^+] [H+] using the following equation: \text {pH}=-\log [\text {H}^+]\quad\quad\quad\quad\;\;\;\text { (Eq. 1a)} pH = −log[H+] (Eq. 1a) The lowercase \text {p} p indicates ``-\text {log}_ {10}" ‘‘−log10".
