Question

For the following salts, provide the following: The cations, anions, and molar coefficients produced when the salts are dissolved in water (writing a balanced reaction is fine) Any subsequent reaction of the cations or anions produced when the salts dissolve in water Whether or not the resulting solution (from the dissolving of the salt in water) is acidic, basic, or neutral, and why. 1. NaNOs ttr0 + NO3 Na neurautrong ete tICn ACIC 2. KCH3COO 3. NH&Cl necrai 4. NaClO 5. MgF2

Answer 1

Ansder 1 Na Can.) +No3 Ca1.) NaNos Car.) weak conjugale eatNAt (a1-) and No3 (a1.) are acid of strong base NaotH And weak Cmugate base of strong acid HNOs espe ctivelf tence mo Yeaction occurs between these ions and Water resulting elution is neutYat So

KCHaco (af) -kt(at.) + C coD (a1.) CHy Coo Cat.)+ Ha0 () CHCaH (af.) + OH(at) CHa Cao is stoong canfugate base of wesk aeid CH3CaoH. Hence it reacts ith ter to produce oH in 8olution Hence resulting folutfon is basic NH4 (a1) ci- (ar) NH4 ca (aq.) N H4 Car)tHoN Hg (a1) + Hao (es) NH i2 stoong cnjugate acid of weak base NH Hence it reacts with aater to produce Haot in Aolution Hence vesulting Aolution is acidic Nat(ar.) +cio Ca1.) Naelo Cai.) HoCu (ar.) 0a1) ceo Cat.) +tho c Resulting Solution is basic (Similar exjkmfia as above) M(1) + 2F (a1.) F CAr.) t H0(R) HF(at.) +OH a1) Resulting Aoution is basic (similar expkation as above)
