Ka = [H + ] [B - ]/ [HB]Benzoic acid dissociates to C6H6COO - and H + - this is a 1:1 ratio so the concentrations are equal hence [H + ] [B -] = [H +] 2 6.3x10-5 = [H +] 2 /0.16.3x10-6 = [H +] 2 therefore H + concentration is 0.0025MpH = -log ([H + ]) therefore pH = -log (0.0025M) = 2.61 Answered by Michael B. popupdiv.style.MsTransition="all 1s ease"; }; -o-transition: all 1s ease-in-out; blockingdiv.id = 'sgt_blocking_layer'; } Colorless crystalline solid benzoic acid having faint pleasant odor is selected for present work due to its solubility in acetone, benzene, CCl4, CHCl3, alcohol, ethyl ether, hexane, phenyls, liquid ammonia, acetates etc. It reacts with sodium hydrogen carbonate to give effervescence of carbon dioxide gas. var postparam='fpusuggestions='+encodeURIComponent(convert(document.getElementById("fpusuggestions").value))+'&fpusuggestemail='+encodeURIComponent(convert(document.getElementById("fpusuggestemail").value)); 2 Names and Identifiers Expand this section. Solubility of benzoic acid in different pH buffer solutions was analyzed by titration method. Therapeutically Benzoic acid helps prevent infection caused by bacteria. 1 it was concluded that solubility in pH buffer solutions in acidic medium was slightly higher than basic pH due to ionic dissociation. Since benzoic acid is much more soluble in hot water as compared to cold, small amounts of hot water are added to dissolve the benzoic acid. Human data on benzoic acid toxicity are available from early oral … { -moz-transition: all 1s ease-in-out; 5. pH of Benzoic Acid. Modern Physical Metallurgy.
