WebApr 10, 2024 · pK b values. Because Kb values are usually very small numbers, sometimes chemists prefer to work with pK b values, that is: pK b = -log K b. Table \(\PageIndex{1}\) shows the pK b values for several bases. Notice that the stronger the base, the higher the K b values but the lower its pK b. WebJun 11, 2024 · Solve the equation for Kb by dividing the Kw by the Ka. You then obtain the equation Kb = Kw / Ka. Put the values from the problem into the equation. For example, …
Calculate pH of Strong Bases (Alkalis) NaOH, KOH
WebSo, 50.0 mL would be 0.0500 liters. So this would be 0.0500 liters. Once again, solve for moles. So, 0.200 times 0.0500 gives us 0.0100 moles of acetic acids. So notice we have the same number of moles of acid as we do of base. And the base is going to neutralize the acid. Let's go ahead and write the reaction.
