In a buffer solution made up of equal concentration of acetic acid (CH3COOH) and sodium acetate (CH3COONa), which component is used to buffer against added OH–? In other words, at the half-equivalence point of the titration of CH3COOH with NaOH, addition of a few milliliters of NaOH(aq), say, at 0.001 M concentration should have what consequence? A. H2O reacts with OH–

B. CH3COOH reacts with OH–

C. H+ reacts with OH–

D. Na+ reacts with OH–

E. CH3COO– reacts with OH–

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
