Heterogenous And Filtrated Using Filter Paper

Improved Essays
The mixture of salt and sand is heterogenous and their physical properties can be used to separate it. To separate sand and NaCl it must be diluted with water then filtrated using filter paper. The residual water is full of dissolved NaCl since NaCl is water soluble. The NaCl can dissolve in water because of water’s emergent property; versatility as a solvent. Because water is polar, it can break apart other molecules until the molecules are bonded with water. To separate the soluble NaCl from the water a physical change must occur and the water must be heated and evaporated into vapor.
Mass was calculated with 2 decimal points because our scale recorded mass with 2 decimal points. Because the mass of the beaker was subtracted from the mass

    In this Beanium lab, the objective was to make sense of the numbers used to calculate average atomic mass. By separating, counting, and weighing beans we were able to create the numbers used to calculate the weight of one bean. From there, we could use the total number of beans to produce the percent abundance for each type of bean. These were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think through the importance of finding the average atomic mass and not just using a single isotope for an element.…

    Mass of dry filter paper 0.70 grams Mass of Calcium carbonate and filter paper 2.58 grams Mass of calcium carbonate 1.88 grams One source of error that occurred during our experiment was spilling the mixture. While we were filtering the mixture, we spilled a small drop of the mixture onto the counter. Another error that could've occurred during this experiment was with the measuring device used because whenever we measured an object, if we moved the object to the middle or side of the electronic balance, it would show a number differing by approximately 0.1 gram each time. This error occurred due to our lack of attention, after pouring the mixture into the erlenmeyer flask.…

    Purpose: The purpose of this experiment was to determine the percent of chlorine in an unknown soluble salt through using gravimetric techniques. The unknown salt was dissolved in water and the chloride ions were precipitated using silver nitrate which produced silver chloride. The silver chloride was then separated by filtration techniques and through this the amount of chlorine in the original salt was able to be calculated. It is expected that the chlorine percent will be around 55.95% because that is the accepted value of chlorine content in the unknown salt.…

    Furthermore, all 6 properties tested further solidified suspicions of the identity of the salt. Salt #287’s properties were initially investigated through a lab test to determine if the salt was Hygroscopic, Deliquescent, Efflorescent or none, and when the salt was left to react with the environment, it was found that the mass of the salt did not change from the initial mass over a course of 15 minutes, which would indicate the salt does not absorb water or lose water and does not have the above properties. Results found in this test are consistent with known properties of Sodium Chloride, being that it is not Hygroscopic, Efflorescent or Deliquescent. Thus, based on this experiment solely, it is not ensured that the salt is Sodium Chloride as 3 other salts share this…

    When using a 100 mL graduated cylinder marked every 1 mL, there should be one decimal places in each reading. The first decimal place is an estimated because the graduated cylinder is marked for every 1 mL. The final definitive number is in the ones place, so the tenth place should be estimated, as the last digit of measurement is usually estimated. For example, on a 100ml graduated cylinder marked every 1 mL, a sample reading would be 75.6mL, three significant figures, because 75 would be shown in the graduated cylinder and I would estimate the tenth digit to be 6. I decided that .0304 g has three significant figures because the first zero is is considered a place holding zero, so it is excluded, while the zero between three and four is included…
