It measures how completely an acid dissociates in an aqueous solution. The larger the value of Ka, the stronger the acid as acid largely dissociates into its ions. Ka to pKa employee management software hospitalityWebThe pKa is the special pH for that molecule. Below that pH, the molecule will be bonded to an H+ ion. Above that pH, it will not. Right at that pH, it'll be fifty-fifty. So, like, acetic acid (CH3COOH) has a pKa of 4.75. So, below pH 4.75, all the acetic acid molecules have their H+ ions attached. employee management system django githubdraw awesome youtube
