When titrating an acid with a base, it is not unusal to a P^H that is different

Question

When titrating an acid with a base, it is not unusal to a P^H that is different from 7.0 at the equivalence point. Which acid and base combination would produce an acidic solution at the equivalence point? NaOH and CH_3COOH CH_3NH_3 and HCI KOH and HNO_3 NaOH and HNO_2 None of these will produce an acidic solution. The molecule NH_2CH_2NH_2 will exhibit two equivalence points when titrated with HCI. Which plot correctly shows the location of these two equivalence points? BD and by the collar that slides on rod AE. Knowing that at the instant considered the rod rotate clockwise with constant angular velocities, determine for the give data the velocity of pin P. 15.150 omega_AE=8 rad/s, omegaBD=3 rads/s 15.151=7 rads/s omega= 4.8 rads/s

Explanation / Answer

A strong acid will react with a weak base to form an acidic (pH < 7) solution.

Now identify a strong acid/weak base pair in the list.

Its B. CH3NH3 and HCL

For second question B is correct diagram.
