HSO SO HNO NO HF F CH COOH CH COO H CO HCO H S HS NH NH HCN CN HCO CO HS S 1 negligile cidity Li O, NOH O, OH strong se Slts re ionic compounds which dissocite in wter to produce ions. They re formed in the neutrliztion rection etween cids nd ses. Depending on the nture of the cids nd ses (strong or wek), the solutions of the slts will e cidic, sic or neutrl. 1. Decide which of the following slts will form cidic, sic or neutrl solutions when dissolved in wter. (Hint: look t the cids nd ses tht formed them) For emple: CH COO ws formed in the rection etween OH nd CH COOH OH is strong se. Its conjugte cid,, hs negligile cidity nd will leve the ph t 7.00, neutrl solution. CH COOH is wek cid, mking its conjugte se, CH COO reltively strong se. It will produce sic solution. ) F ) CN sic sic c) NNO d) RI neutrl neutrl e) NH NO f) N CO cidic sic
2 . Rnk the following 0.1 M queous slt solutions in order of incresing ph. (Hint: write out the rections of the slts wter) ) NO SO S neutrl sic ( ) sic ( 1 ) strongest se ph rnk: NO < SO < S ) NH NO NHSO NHCO N CO cidic cidic sic sic strongest cid strongest se ph rnk: NHSO < NH NO < NHCO < N CO. In n eperiment, it is found tht the phs of three slts, X, Y nd Z re 7.0, 9.0 nd Arrnge the cids, HX, HY nd HZ in order of incresing cid strength. The strongest cid would hve the wekest conjugte se. Weker ses (t equl concentrtions) will hve lower ph vlues (they re less sic). The se strengths must e X < Y < Z The conjugte cids will hve the reverse trend: HZ < HY < HX. Clculte the ph of 0.1 M NCN solution. N does not ffect the ph of the solution CN is wek se with CN H O HCN OH [CN ] [HCN] [OH ] Initil Chnge Equil poh log(1. ph [ HCN][ OH ] [ CN ] ).9 0.
3 5. Suppose tht ml of 0.M CH COOH is comined with ml of 0.M NOH. Wht is the ph of the resulting system? The eqution for this rection is: CH COOH OH CH COO H O (neutrliztion rection) ) How mny moles of CH COO re formed? (ssume the rection goes to completion) 0. mol CH COOH mol CH COOH 0.050L mol 1L solution 0. mol OH mol OH 0.050L mol 1L solution moles CH COOH OH CH COO Initil Chnge Equil This rection would form moles of CH COO ) Wht is the finl volume of the solution? Finl volume is the sum of the components: 50 ml 50 ml 0 ml c) Wht is the concentrtion of CH COO? [CH COO ] mol / 0.0 L M d) Chrcterize CH COO (i.e. wek/strong cid/se). wek se e) Write the rection of the product (CH COO ) nd wter. CH COO H O CH COOH OH f) Set up n ICE tle for the rection nd clculte the ph of the solution. [CH COO ] [CH COOH] [OH ] Initil Chnge Equil poh log(5. ph [ CH COOH ][ OH ] [ CH COO ] )

The conjugte cid will then rect with wter to yield n cidic solution. So moles of NH will form, with concentrtion of 0.050M nd then rect with wter ccording to the eqution NH H O NH H O [NH ] [NH ] [H O ] Initil Chnge Equil ph log(5. [ NH ][ H O ] [ NH ] )

It hs three equilirium epressions ssocited with its rection with wter: H AsO H O H AsO H O H AsO H O HAsO H O HAsO H O AsO H O 6.0 It is wek cid, whose ioniztion constnts decrese mrkedly for the second nd third dissocition rections. The concentrtions of ech of the four species cn e clculted s follows: The vlue of 1 will e used to clculte the concentrtion of H AsO, H AsO nd H O. These concentrtions will not e ffected y the other equiliri. The vlue of will e used to clculte the concentrtion of HAsO, using the previously clculted vlue of H AsO nd H O. The vlue of will e used to clculte the concentrtion of AsO using the previously clculted vlue of HAsO nd the concentrtion of H O, from If we hve 5.0 M solution of H AsO, wht re the concentrtions of ll of the species present? ) First, clculte the following concentrtions using the first ioniztion: [H AsO ] 5.0 [H AsO ] _0.158_ [H O ] _0.158_ [H AsO ] [H AsO ] [H O ] Initil Chnge Equil [ H AsO ][ H O ] [ H AsO ] ) Wht is the ph of this solution? ph log( 0.158)
