Solid

in water, it can not conduct electricity as a solid, and it must conduct electricity as an aqueous solution. Unknown Y met all of these requirements which is why it must be an ionic compound. Unknown X is not an ionic compound because it does not conduct electricity as an aqueous solution and has a low melting point. Unknown X did not pass the 4 test to become…

The initial hypothesis that was made regarding the strength of the solid compounds was supported with this experiment. The hypothesis stated that potassium hydroxide would have the greatest effect on the acidic solution. This was supported here as it had the highest average change in pH by far. On average, the pH value of the acidic solution increased by 12.5. This is significantly higher than the increase of the other solutions, which only increased around a pH of 4. The reason why potassium…

NaOCl was added over a 20 minute period in order to keep the solution testing positive. Next, 0.5 mL of NaHSO3 was added for the solution to test negative. Solution was heated for another 20 minutes and then cooled in an ice bath for 8 minutes. White solid was collected using vacuum…

added to this mixture. Immediately after, the formation of a yellow precipitate (Ammonium Azo-Tetrazolate) was observed. The suspension was left in the refrigerator to cool till the temperature was less than 5 °C. The solid was washed in water, filtered and dried. When the solid was weighed, it yielded a weight of 1.532 grams, which gave an expected yield of 74.43%. Reaction (3) To Make Guanidinium…

Investigating Properties Lab Ishan Godra SCH4U Lab Partner(s): DeSean Lawrence Ms. Boulougouris 10/31/14 Purpose The purpose of this experiment is to analyze the properties of four different types of solids: ionic, polar covalent, non polar covalent, and metallic Hypothesis It is hypothesized the samples which are shown to be insoluble are likely non polar, while soluble samples are polar. Because of the molecular nature of each type of bond, it is hypothesized that polar…

Suspensions: The oral liquid dosage form chosen to formulate was that of a suspension. Given the criteria of Drug Y it was thought best to formulate the drug as a suspension. Suspensions can be defined as ''a class of materials in which one phase, a solid, is dispersed in a second phase, generally a liquid.'' (1) There are many characteristics of suspensions that are relevant when formulating such a dosage form. They are as follows; (1) Whilst in storage the suspended particles can sediment to…

In this experiment, solid-liquid extraction was used to separate trimyristin from the other components in nutmeg. The result was then tested for purity using melting point analysis. This extraction technique uses differing solubilities of components in a chosen solvent system, in this case diethyl ether, as a means of separation. Utilizing this technique, of the original 3.8146 grams of nutmeg, 0.1905 grams of trimyristin were recovered, yielding a 4.99 % composition. This methodology can…

1940s, fishing rods were made of either hollow or solid fiberglass. Hollow fiberglass fishing rods were lighter and more affordable than solid versions, but they were more brittle and subject to breakage, particularly the tip. The solid rods were stronger, but they were also heavier and more expensive than the hollow ones. Shakespeare developed a process that consolidated the benefits of each type of rod by joining a hollow fiberglass base to a solid fiberglass tip. With developments in…

populace since time immemorial. To the greater part, the length of they are not overweight, large or too thin, then they feel they are solid. This is another normal wellbeing misguided judgment that individuals have. Because they are not fat or overweight or even malnourished, doesn't imply that they are essentially sound and that their present weight is the solid weight for their age. As you most likely are aware, overweight or underweight is identified with a few wellbeing issues. Be that…

nitrogen gases from the atmosphere into solid nitrogen compounds that plants can use in the soil. Let's break this concept down. Nitrogen is commonly found as an inert, or nonreactive, gas in the Earth's atmosphere. In fact, 78% of the Earth's atmosphere is nitrogen in its gaseous design. This element is so sufficient that it has been incorporated into all living things on Earth. In order for this to happen, though, that nitrogen gas needs to turn into something solid that can be used by living…
