(Multiple Choice) wat is the Net Ionic Equation for the reaction that occurs when small amounts of .?
a. H + H20-> H3O
b. H + OCl-> HOCL
c. HOCl-> H + OCl
d. H + HOCl-> H2OCl
e. HCl + HOCl -> H2O + Cl2
i have no clue how to figure out this one!! thanxx
Answer:
In a buffer solution, the ions interact in such a way as to minimize the effect of adding acid or base to the solution, keeping the pH stable.
In this case, you're adding acid, which means adding H+, so your answer is going to require some mechanism for tying up that excess H+. Based on that information, the only possible answer is b)
HOCl (hypochlorous acid) is a weak acid, thus a fairly strong base. So, in this case, adding HCl means that the excess OCl- from the sodium hypochlorite (laundry bleach) will combine with the excess H+ to form HOCl.
H+ + OCl- ===> HOCl
I hope that helps.
