A dilute solution of which acid is most likely to produce a reduction product other than H2 when it reacts with a metal? A)HF B)HCL C)HNO3 D)H2SO4 Answer is C. I know it has something to do with it producing oxygen, but I really don't understand where that comes from. Plea...
Determine the volume of 0.125 M NaOH required to titrate to the equivalence point 25.0 mL of a 0.175 M solution of a monoprotic weak acid that is 20% ionized. Answer is 35.0 mL. How do you find it?! It's been a really long time since we talked about titrations. Please help (:
