Xavier and Fatima both work at a local convenience store, Mac. Their supervisor, Gerald, has just decided to make them take turn
s working alone in the store in the evenings. This decision makes both Xavier and Fatima very nervous. Someone could rob them or assault them. No one would know because it is late in the evenings. Gerald specifically wants them to take turns with the evening shift because he doesn’t want to have more than one employee working at the same time so he can save money.
Who is the employer?
Who is Gerald?
What is the safety issue in this situation?
What should Xavier and Fatima do about making sure the situation would be more safe?
The solution shall contain only (and water) at the equivalence point. Both potassium hydroxide and nitric acid exist as strong electrolytes. As a result, , the salt derived from a reaction between the two species would undergo hydrolysis of a negligible extent. This neutralization reaction therefore be neutral at the equilibrium point.
The question states that the solution is "titrated with a ... nitric acid solution" indicating that is added to the initially-basic solution. PH value of the solution would keep decreasing as the volume of the acid added increases. The final solution would be acidic as it contains not only water and , but some as well. Bromothymol blue would therefore demonstrates a yellow color, the color it present in an acidic solution, at the end of the titration.
