The iodide ion concentration in a solution may be determined by the precipitation of silver iodide. Ag (aq) I-(aq) AgI(s) A student finds that 15.44 mL of 0.5080 M silver nitrate is needed to precipitate all of the iodide ion in a 50.00-mL sample of an unknown. What is the molarity of the iodide ion in the student's unknown

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
