Title: How do I calculate Ka and pKa? Post by: smith39d on Apr 15, 2013 I'm only given the pH (3.75) and the concentration (0.01M). Please, give me a couple of examples so I can use the precision to test what I'm doing. Thanks!
Should I Subtract this to get Ka? 3.75pH - 0.01M = 3.75 Title: How do I calculate Ka and pKa? Post by: judypn on Apr 15, 2013 From the pH u can know it is a weak acid so we can use the law:
pH= pKa + pCa, where Ca is the concentration of the acid so u can easily obtain pKa and Ka as u have pH and Ca |
