The pKa of phenol (C6H5OH) is 9.95. Suppose that the composition of the mixture somewhere between 25% and 75% NaC6H5O by mass. If 1.000 g of the sample mixture, dissolved in enough water to make 20.00 mL of solution, is going to be titrated with 0.100-M HCl, which of the indicators listed in this lab would be the best for identifying the equivalence point? Justify your answer with clear reasoning and any necessary calculations.

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.
