This is the net ionic equation for the complete neutralization of a generic diprotic acid with sodium hydroxide: H2A (aq) + 2 NaOH (aq) + 2 H20 (1) + Na2A (aq) a. OH- (aq) + H+ (aq) â H20 (1) b. 2 Na+ (aq) + A2- (aq) - Na2Cl (s) c. 2 OH- (aq) + 2 H+ (aq) + 2 H20

Water is initially present in a state where its molecules are far apart. during a change of state, its molecules slow down. which change of state has most likely taken place? from a gas to a liquid from a liquid to a gas from a solid to a liquid from a gas to a plasma

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
