7. Acid/base strength. (12 pts total) a. Put these in order of increasing basicity(6 pts) C03-2, I-, NH2-, HS04\", ??\", NO3- b. Put these in order of increasing acidity(6 pts)
Solution
a. CO 3 -2 .> NH 3 > HOH > HSO 4 -1 > NO3 -1 > HI
REASON = add H + to every ion , then compare the acidic strngth amoung all , then revese the order of acidic strength to get basisity order .
ACIDIC STRENGTH ORDER = HI > HNO 3 > H 2 SO 4 > HOH > NH 3 > HCO 3 -.
# HCO3 - HAS ANEGATIVE SIGN THATS WHY , REMOVAL OF HYDROGEN IS DIFFICULT
