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...
When a generic acid (HA) dissolves in water, it donates a proton, and the product of the reaction consists of H3O+and A-, which is the conjugate base of the reaction. Depending on the relative abilities of HA to donate protons and A-to accept them, the reaction can also proceed in t...
A 3.60-L solution of 1.60 x 10^-3 M Pb(NO3)2 is mixed with a 0.60-L solution of 0.53 M NaCl. Calculate Qc for the dissolution of PbCl2 (Ksp = 1.6 x 10^-5). No precipitate has formed. Determine whether or not a precipitate will form if 75 mL ...
Calculate the pH of a 1.51 mol/L solution of hydrofluoric acid. The pKa of HF is 3.17. Calculate the pH of a buffer solution that is 0.40 M in both HC2H3O2 and NaC2H3O2. Between benzoic acid and acetic acid, which is a stronger acid without looking to pKa value? Why ...
How many moles of NaOH are needed to react completely with the sulfuric a Calculate the molarity of a solution containing 10.0 grams of H2SO4 and 800.0 mL of water. Also, solve for pOH and pH. If 40 mL of sulfuric acid...
