Equilibrium Chloride Affect The Temperature Of Water

453 Words2 Pages

The experiment that was done was to figure out “Does the amount of calcium chloride affect the temperature of water?” For the procedure, the experiment asked to record the initial temperature of 75 mL of water. The first trial said to add zero scoops of calcium chloride and stir for two minutes to record the temperature. Once the first temperature was recorded, it must be written from the difference between the initial temperature and the new temperature. Next, it asked to add one scoop of calcium chloride and stir for two minutes and record. Lastly, it told us to repeat the same steps until we had three calcium chloride scoops in the beaker and repeat for two more trials for accurate results. To sum up the experiment, it said to record the average change in temperatures to the class averages to graph a bar graph comparing both of the averages. That’s the procedure on how to conduct the experiment correctly.

The averages that my group received for zero scoops were 0.5 degrees Celsius, one scoop was 6.5 degrees …show more content…

The error was how fast the person was spinning the water. It could have changed the temperature of the water easily, by how much calcium chloride was dissolved. Another error was how much calcium chloride was added, it told us to add one scoop, instead of a more accurate measurement, for example, one tablespoon. The scoop could have been not filled all the way, or filled too much. To improve this experiment, we could have had accurate measurements and spinning every 10 seconds. After finishing the experiment, I learned that calcium chloride is flaky and has a powder consistency and when it is in liquid form, it’s colorless. The only question I have is that what would happen if you put calcium chloride in very hot water. In the end, this experiment overall was very educational to learn how much the temperature rises just from calcium chloride and

After seeing this data the two most effective look chemical at resisting energy was CaCl2 and LiCl. So we looked at the price of both of this chemical CaCl2 cost 6.55$ per 500g and LiCl cost 32.75$ per 500g because CaCl2 was substantially cheaper we decide to chose it to use in own hand warmer. We calculated that it would take 22g of CaCl2 to create a 20oC increase in temperature of 100ml of water. Some sources of error in this lab, would be heat escape from not be able to replace the lid of the calorement went adding chemical into it, inaccuracies in the balance, and not waiting of the proper time to recode the

How Fast Does Alka Seltzer Make Gas

621 Words | 3 Pages

The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react.

In the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

Empirical Formula Of Copper Chloride Lab Report

729 Words | 3 Pages

As the water was added to the heated sample, the solid copper chloride began to dissolve into a pretty blue-green solution, as a result of the compound breaking apart into individual Cu2+ and Cl- ions. When the water was first mixed with the copper chloride, it dissolved the solid pretty slowly, turning into a sort of mush at first. However, eventually, the water dissolved all of the solid copper chloride and the solution was homogenous. Since the compound just changed physical form, from solid to liquid, this change was purely physical. Just as in the first part of the experiment, the chemical character of the compound was not altered, so the compound did not experience a chemical change.

Lab Report: Diffusion And Osmosis

In this lab we used two processes called Diffusion and Osmosis. Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. Diffusion is a process that requires no energy and involves smaller non-polar molecules. In Figure 1 you can see the molecules spreading throughout the glass from the area of high concentration, so that the areas with low concentration are filled evenly as well. The other process was osmosis.

How The Hotplate And Water Affects The Temperature Of Chocolates

224 Words | 1 Pages

In this experiment, the question being asked is, how does the temperature of the hotplate and water affect how fast the chocolate melts? The three types of chocolate that will be used are white, 70%, and 90%. It was hypothesized that the white chocolate will probably melt the fastest because there is more cocoa butter and sugar and there are no cocoa solids. The 70% cocoa chocolate will most likely melt the second fastest because of it has the least amount of cocoa solids. The 90% cocoa chocolate will, in all likelihood, melt the slowest because it has the most cocoa solids.

Research question What is the effect of temperature Amylase activity? Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. They do this by decreasing the activation energy(the energy needed to start the reaction) of a chemical reaction. The enzyme present in our saliva is called Amylase. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules.

Water Hydration Lab Report

603 Words | 3 Pages

In this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up
