Solubility

The mass of the individual recovered components make up the total mass of the 1:1:1 mixture of Benzoic acid, Benzocaine, and Fluorenone. Because the ratio is 1:1:1, that means all of the components are equally weighted in the total weight of the mixture. Since the starting weight of the 1:1:1 heterogeneous mixture was 0.618 g, you can assume that the 0.618 g is made up of the three components each weighing 0.206 g. This came from dividing the starting weight by 3, since there are three components

The information above shows the results observed from the experiment. The unknown substance was first observed to be a white, powder that had no smell. When it was mixed with the water, it produced a clear odorless solution. The pH was taken immediately from the solution once it was mixed properly. The pH came out to a 10 on a 14 level scale. This indicated that the solution was a strong alkaline base. With this information, the list of possible solutions are narrowed down to only basic solutions

Energy Story, Hands-On Science with Squishy Circuits, and Conducting Solutions all have one important similarity: they all explain how electricity works! These three sources explain very different things, but they always end up coming back to the main objective of electricity. Energy Story explained how atoms function, and how they, as a whole, are passed through circuits to create electricity. Conducting Solutions explains how liquid solutions including Ammonia and Vinegar are stronger together

The primary goals of this experiment concern expanding upon the concept of molar mass and its applications to the study of chemistry (Beran, 2014). To this end, the effect of an unknown solute on the freezing point of a solvent, cyclohexane, was measured and noted in order to determine a positive or negative relationship between the two variables (Beran, 2014). Additionally, the molar mass of the nonvolatile and nonelectrolyte solid solute was ascertained (Beran, 2014). Introduction: When one examines

Contamination of test tubes, due to inadequate cleaning before the experiment. Having test tubes being contaminated may be because of inadequate cleaning before the experiment. By having contaminants on the test tube even before you start the practical, your experiment may already be inaccurate as the contaminants may mix with the solutions that you drop. To improve this make sure to clean the test tubes thoroughly. To improve this rinse/wash the test tubes 2-3 times if necessary. Contamination

Synthesis of Aspirin Ling Tecson Gamido, Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid, or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride, both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order

Title: Did the amount of salt used in ice cream formation effect the mass of ice cream produced? Purpose To discover whether varied amounts of salt used in ice cream formation effected the mass of the final product. Background Information In order for water or milk to freeze, the temperature needs to be at or below 0ºC. In order to lower the freezing point of solution, different solutes can be added. A solution is created by dissolving a solute into a solvent, such as dissolving sugar (solute)

Co-precipitation Co-precipitation is an important technique widely used for separation and pre-concentration of analytes from various samples [examples]. It is adopted when direct precipitation cannot separate the desired metal ions due to their low concentrations in the sample (Bulut VN et al. 2008). Various mechanisms including surface adsorption, ion exchange, surface precipitation and occlusion are involved in co-precipitation technique [ ]. Metals, at trace levels, react with an organic or inorganic

More recently, a reverse micelle based polyacrylate coating method was undertaken to obtain various functional nanorods [24]. The micelle based coating was shown to be very versatile as the coating produced water soluble GNRs without particle aggregation. This coating developed could absorb a variety of functional groups including primary amines, ethylene glycol and fluorescein. This makes them much more suited for biomedical applications. This more recent study, although not highly cited does make
