Solving for molarity equation
WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base. WebSep 1, 2024 · Solutions have several properties. While some are a function of volume, others are a function of molecular mass.One such property is molality. It is the property of a …
