Electrolytes: Ionic Bond and Sodium Chloride Essay

c) Record the amount of substance that dissolved – all, some, a little, or none.

For part B, 50 mL of an assigned 50 mL pH solution of either 1 M HCl, 1 M NaOH, lemon juice, and 50 mL of household bleach all in separate 250 mL beakers are to be used. For part C, a hot plate or ice are to be used to make the 1.0 mL assigned temperature specific water. This experiment will also use the 1.0 mL of 0.1 Phosphate buffer.

Purpose: The purpose of this lab is to familiarize you with osmosis and, specifically, what happens to cells when they are exposed to solutions of differing tonicities.

Each laboratory experiment must be read and carefully studied before coming to the laboratory. This must be done to ensure that each student is thoroughly familiar with the principles, procedures, calculations, and anything else with the exercises may be involved.

1. Make sure that you understand the objective of the lab(s) and the requirements for successfully performing them.

•Be sure to write a detailed procedure for each lab design so that the same procedure can be followed accurately by anyone who reads it. Include details on the setup, the control of variables, and how the rate of each trial will be compared.

In paragraph two, it states "Pure water contains very few ions, so it does not conduct electricity well. When table salt is dissolved in water, the solution conducts very well, because the solutions contain ions.". In paragraph four, it explains how laundry ammonia can conduct electricity. It states "When ammonia dissolves in water, it reacts with the water and forms a few ions.". In conclusion, paragraph five explains more about how ammonia can cause electricity when it is put into a solution with vinegar.

Complete the experiment and save the PDF lab report. Do not answer the questions in the PDF lab report. Use the data in the PDF lab report

The first two questions will be answered during the introduction of the lesson and the rest will be the laboratory analysis questions. These will get the students to analyze and make sense of their lab results.

In this gummy bear lab, the goal was to see the movement of water in cells depending on the concentration of solutes in the environment. The control group was the type of water used. The research question for this experiment was, how does concentration of solute in the environment affect water movement in cells? The hypothesis thought of for this question was that the salt water would enlarge the gummy bear the most. The distilled water would not enlarge the gummy bear as much as the salt water.

In the last article "Conducting Solutions" the main purpose is that it explains how different materials conduct electricity. In this passage, they describe an experiment with sugar and water. It says that when sugar is dissolved in water, the solution does not conduct electricity because there are no ions in the solution. It also describes experiments with vinegar and ammonia. It says that they work well as a mixture because the ammonia reacts with the acid in vinegar and hey form a lot of

1. Using the information provided in the Introduction and your observations from Part 1, hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint.

It would respond to a hypotonic solution. Distilled water has the best hypotonic solution due to that, the water molecules would flow in the tubing because of the optimum concentrate in solutes of the tube. (Cinnamon L. , 47)

• Sometimes the best thing to do for your method is to draw a diagram of the experimental set up and refer to it. That’s

Analyze the flow chart drawn above using the basic question. (How, What, When, Where &
