Lab Manual Water Boils

460 Words2 Pages

Before the experiment began I had to read the laboratory manual, while I read it what grabbed my attention was stated in the lab manual water boils at 100 degrees Celsius. Just as I continued to read the manual as an assignment, I was going to “investigate the relationship between the concentration of solutes in water and the temperature at which the water boils” for the class the next day. At this point, my curiosity began the experiment. I started to think how long it took for the water to boil? A question arose, by adding sodium chloride to the water will the temperature change for the water to boil? If it took 100 degrees Celsius to boil pure water. Then by adding sodium chloride to the water, it would take greater heat to boiling the water. For this reason, the temperature would increase to reach the boiling point. My prediction was that the temperature of the water would be greater as sodium chloride added to the water. The more sodium chloride added, the more the temperate will increase. Next, I began the process of the experiment in class. …show more content…

Next, I had to test the different amount of sodium chloride in the water as I took four 250 ml beakers and labeled them A, B, C and D. Then added 100 ml solution containing 0, 1, 3, and 5, M sodium chloride in the each beaker. After I had set up the tripod and non-asbestos pad over a bunsen burner, I placed the solution from the beakers to the cylinder on the tripod and began to boil each solution one at a time and record the temperatures with the thermometer. The data that I collected is in the chart

A hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.

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

Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap

The scientists will conduct the experiment by taking four cups of water one that is just salt mixed with water, another that is just water, a third cup that is just ice water and finally a forth cup that is vinegar and water mixed. After that the scientists will drop one Alka-Seltzer tablet into each cup and see how long it takes for it to completely dissolve. The scientists will conduct these three times for

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.

When three teaspoons of salt were added to water, the average freezing point was 22.2°F. The relationship between the amount of salt added to water and the freezing point of water was as the amount of salt increased, the freezing point decreased. My hypothesis was supported by my data because the average freezing point of the water with three teaspoons of salt was 5.8°F less than the average freezing point of water with one teaspoon of salt. My results concluded that increasing the amount of salt added to water decreases the freezing point of that water. Another question I would like to ask is how does the amount of salt affect the boiling point of

Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.

Furthermore, the value attained for the calorimeter constant was 0.1748 KJ/°C, this value allowed to apply the correction for heat loss to the calorimeter. However, during the calculation for the calorimeter constant, the assumption that the specific heat of water was 4.184 J 〖deg〗^(-1) g^(-1). The concentration of NaOH was attained when assuming no heat loss was 0.8170 M and including the heat loss the concentration of NaOH was 0.9493 M. These values are very close to the expected value of the concentration, which is 1.071M considering the experimental error is only about 11 percent off.

In the mountains, because of the altitude, the lower the atmospheric pressure so water boils at a lower temperature 59. strong base and strong acid relationship This questions requires basic stoichiometry and understanding that the reaction between a strong acid and a strong base will result in a salt and water and if it’s not a strong base then it will dissociate into some degree into OH- 60. gas laws, standard conditions, PV=nRT For this question, it is simple to all that you need to do is rearrange the equation PV=nRT to solve for pressure and convert the measurements to the ones used in the ideal gas law, K, mols, L and atm 61. phase changes, heat of combustion, heat of solution, heat of vaporization, exothermic and endothermic reactions, thermochemistry

The boiling point of the solution will be higher than that of the pure solvent itself. The boiling point of a liquid is the temperature at which its vapor pressure is to equal the atmospheric pressure. When a solute is added there are less solvent molecules near the surface and the solvent’s vapor pressure will decrease, so the vapor pressure of the solution will be less than that of the solvent. For the vapor pressure to reach the atmospheric pressure, a higher temperature must be reached, which means the boiling point is elevated. According to this theory, adding salt to water would make the boiling point higher, and make it harder to reach the boiling point.
