content of your paragraph.
1. What was your hypothesis? According to your data, was your hypothesis was correct?
2. Why did some substances require larger additions before a color change was seen? What does this indicate about
the strength of the acid or base?
3. What happened in the final step of the experiment? What does the final color indicate?
4. To what extent was this experiment useful in determining pH? Could a specific pH be determined using this
procedure?
5. Why are acid and base indicators important? How could they be used in everyday life?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
