This is the third time I'm trying to post and physicsforums keeps saying that some security token is missing and I lose the post. This feature is very important when you are trying to calculate the pH of the solution. What is the chemical equation that represents the weak acid Is a solution with H+ = 4.3 x 10-5 acidic, basic, or neutral? Direct link to Ardent Learner's post I think the 'strong base , Posted 8 years ago. and we're going to take 5.6 x 10-10, and we're 4. The conjugate bases of strong acids, and the conjugate acids of strong bases, do not react appreciably with water, whereas this is not the case with weak acids and bases. pH of Solution. Explain. Is an aqueous solution with OH- = 8.0 x 10-4 M acidic, basic, or neutral? No mistakes. Is a solution with OH- = 4.4 x 10-3 M acidic, basic, or neutral? Concept Check 17.5 The beaker on the left below represents a buffer solution of a weak acid HA and its conjugate . Explain. it would be X as well. 2 No Brain Too Small CHEMISTRY AS 91392 . Is an aqueous solution with OH- = 2.37 x 10-8 M acidic, basic, or neutral? The concentration of Our calculator may ask you for the concentration of the solution. Direct link to RogerP's post This is something you lea, Posted 6 years ago. [OH^-]= 7.7 x 10^-9 M is it; Determine whether a 0.0100 M NaF solution is acidic, basic, or neutral. The acid and base chart is a reference table designed to make determining the strength of acids and bases simpler.
