A student pulls a bottle of TRIS off a shelf and notes that the bottle says, “TRIS (basic form), pK a = 8.3”. The student tells we that if we add 0.1 mol of this compound to 100 mL of water, the pH will be 8.3. Explanation required that student is correct or not. Concept Introduction: There are associated scales within the chemistry utilized to find out how basic and acidic a solution is, as well as the strength of bases and acids. Though most familiar is pH scale, K a , pKa, K b and pK b are the common calculation which offer understanding into acid-base reactions.
