WebMar 13, 2024 · Bases have a pH greater than 7. pOH is calculated for the base solutions instead of pH. The dissociation constant for weak bases is always lower than for strong bases, and it determines the strength of a base. Weak bases can create buffer solutions, just like weak acids. Frequently Asked Questions 1. What is a weak base characteristic?
WebSince p K a + p K b = 14, you get p K a = 10.64 for the methylammonium cation. H C l protonates methylamine. The amount of methylammonium increases by the same amount methylamine decreases. So. p K a = p H + log ( [ H A] [ A X −]) = p H + log ( x 10 m m o l − x) lets you calculate the value x of H C l needed to obtain the desired p H. WebWeak Base: Compounds that produce a minimal amount of OH− O H − ions that are mostly constituted of the undissociated form. pOH equation: pOH= −log(OH−) p O H = − l o g ( O …
