The ph of 89 mm nh4oh solution is 11.1 at 25 °c and 1 atm. (a) determine the dissociation constant of this weak electrolyte. (b) when the nh4oh solution is diluted to 0.01 m (ie, 10 mm), determine the degree of the dissociation and the ph of the solution. (c) how does the degree of dissociation of nh4oh solution change (increases or decreases) with the solution concentration?

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
