Aniline hydrochloride, [C6H5NH3]Cl, is a weak acid. Its conjugate base is the weak base aniline, C6H5NH2. Ka = 2.40 X 10^-5. Required:
1. Calculate pH at points if 50 mL of 0.100 aniline hydrochloride is titrated with 0.185 M NaOH.
2. Calculate the pH (a)before titration begins (b)at E. P (c) at the midpoint (d) after 20 mL of NaOH (e) after 30 mL of NaOH

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
