Write the net ionic equations for three precipitate-forming reactions (from the table above) when you combined the reagents. Hint: In Table 1, there are many reactions that form precipitates - just choose three of them. 3 pts 2. Describe how you would prepare the following two solutions. Be sure to include the type of glassware which you would use and as much detail as necessary for someone to actually prepare the solution using good laboratory technique. 2 pts each • 250 mL of a 10% NaCl (w/v) from solid Naci • 250 mL of 1 M HCl from 12 M hydrochloric acid. 3.

Answer 1

Broswoe . along with their 1. The three precipitats formed lonie equation is swein as a. Bät t2cł +2H + soa → b. 4 t + ci + Agt + NO3 → c. Q A g +2NO3 + 2Na+ co → from AgNO3 Na2CO3 Basott a Hel Agold + HNO3 white AgaCO3d+ 2 MaNO3 Yellowish from PROBLEM a a. 250 ml of 10% Nach (w/v) from Naclcss Glass were used volumetne flask, kipette, beaker. * weigh exacthy 250 g of Naol & dissolve in 250 mL of DISH. H2O in a 250 ml volunuetre blask. b. 250 ml of IM Hal from 12m Hel. Glass ware used volumetné flask, pipette, To prepare 250 mL of im Hel use, deletion formella Miri = Ma Va. 250 X1M = 12 xV2. 280 = 20.03 mL Thus we have to take 129.17 ml of water in a 250 ml volumetue flask. To ! this we have to add 20.03 ml of 1 12 M Hel to make up IM 250 ml Hel solution. 12
