Calculate the pKa value for the following acids. Nitrous …
WebThe pKa value for HNO2 is 3.40. Calculate the pH of the buffer after the addition of 1.173 mL. An acid–base buffer is a solution that resists changes in pH when a small amount of … WebDec 16, 2024 · This value can vary depending on factors such the charge of the acid. I f this charge can be easily distributed in resonance structures, the compound is more acidic, and therefore the pKa value is lower. The lower the pKa, the more acidic the compound is. So calculating the pKa on every structure we have: HF: pKa = -log(3.5x10^-4) = 3.46. HNO2 ... WebScience. Chemistry. Chemistry questions and answers.
