1. What does a buffer do? It keeps the pH of a solution from changing very much. It maintains the amount of acid in a solution It maintains the amount of base in a solution It keeps the pH of a solution from changing at all. 2. Which of these is a way to calculate the pH...
Calculate the pH of an alkaline (or basic) buffer solution. You can rewrite the Henderson-Hasselbalch equation for bases: pOH = pKb + log ([B+]/[BOH]), where "pKb" is the base's dissociation constant, "[B+]" stands for the concentration of a base's conjugate acid and "[BOH]" i...

Calculate the pH of a buffer solution prepared from 0.155 mol of phosphoric acid, 0.250 mol of KH_2PO_4, and enough water to make 0.500 L of solution. You are preparing 500 mL of Denaturation Buffer containing 1.5 M NaCl and 0.5 M ...
It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=m(soln)cΔT =75.0 x 4.184 x (27.21-25) =693.5J =0.6935kJ ...
Then we x by 10 to get the number of moles in 100cm3 of solution, right? Logged Borek Mr. pH Administrator Deity Member Posts: 27887 Mole Snacks: +1816/-412 Gender: I am known to be occasionally wrong. Re: How to calculate the number of moles of Fe2+ produced in the reaction...
the solution in your beaker is a "buffer solution," one which resists changes in pH when you add small amounts of acid. You can represent the extent to which your acid dissociates — and thus changes the solution's pH — using its "pKa" value, and you can calculate this value using...
Decide on the pH for your buffer. This pH should be within one pH unit from the pKa of the acid/conjugate base. So, you can prepare a buffer at pH 2 or pH 7, for example, but pH 9 would be pushing it. Use theHenderson-Hasselbachequation to calculate how much acid and base you ...
