Bleach is used to disinfect water. For disinfection to work effectively, we want to have
hypochlorous acid HOCl instead of hypochlorite OCl-. Find pH so that at least 95% of bleach is
in hypochlorous form.

A) HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.087 M in NaClO at 25 °C? The hint is: Na is a spectator ion in this situation. Start by finding the Kb of ClO–. B) A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate...

Show work, draw a picture, label your variables. (4pts) We want to construct a box whose base length is 4 times the base width. The material used to build the top and bottom cost $10 sq foot and material used to build the sides cost $6 sq foot. If the box must have a volume of 60 cubic feet, determine the dimensions that will minimize the cost to build the box and find the minimum cost box. * Give your...

Our new service manager starts work today! This is great news! As our business starts to expand, we must move our software project along. You will need to talk to some of our employees to better understand the functionality and requirements for the proposed system. This is important because they are the key stakeholders of the system. You should make a list of employees who you will want to interview. I suggest that you learn the process for scheduling an...

A debate rages whether or not bottled water is worth the cost. The National Resource Defense Council concludes, “there is no assurance that bottled water it is any cleaner or safer than tap (water).” But, in addition to the safety issue, many people prefer the taste of bottled water to tap water, or so they say! Let’s suppose that the city council members of Corvallis are trying to show that the city of Corvallis tap water tastes just as good...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
