Document Summary
Hf v strong acid because f is small, therefore bond is shorter. 10 base must contain oh- if water is to be formed. Weak acid and strong base is a reaction that goes to completion. Increase [a-], reaction shifts to use up added [a-] therefore making more [ha] [ha] increases because of the addition of [a-] (le chatelier"s principle) this is called the common-ion effect. Shift to the reactants" side therefore use up some of the products therefore less [h3o] therefore more [a-] to keep everything balanced. [h3o+] = x = 1. 8x10^-5 m ph = 4. 74. Ka = [products]/[reactants] = (0. 50+x)(x)/(0. 50-x) = 1. 8x10^-5. Oh- + ch3cooh -> water + ch3coo- Strong base added very reactive ph = 2. 52 www. notesolution. com ph = 4. 74. [h3o+] = x ph = 3. 36 adding base therefore expect ph increases. Ka = [products]/[reactants] = (0. 020m+x)(x)/(0. 48-x) = 1. 8x10^-5. Oh- + ch3cooh -> water + ch3coo_ Ch3cooh + water -> ch3coo- + h3o+
