In part 1 the results of the solubility do not agree with the with rules of solubility most likely because we put too much solid in the test tubes and not enough water to dissolve it. They should have dissolved because the anything with nitrate should be soluble. With the pH‚ when the mixture where compared with the chart all of them except NaCl where a shade of blue which means that they have a pH of 8-14‚ depending on the darkness of the shade‚ meaning that they are a basic solution.

world that are soluble‚ however‚ these chemicals have to follow a set of rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch (2015) the Solubility Rules are as

We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions

Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that

Description We will be mixing ionic compounds in solute-solute and solvent solute interactions. We will be combining sodium‚ potassium‚ calcium‚ magnesium‚ copper‚ iron‚ nickel and silver and some anions like chloride‚ sulfate‚ nitrate

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Introduction For the last week‚ specific tests had to be applied to determine the unknown solid that was given out randomly. Physical tests‚ solubility test‚ characteristic tests‚ NMR spectrums‚ and IR spectrums were all utilized to distinguish the identity of the solid. These assessments and a couple additional tests will be utilized again to determine the unknown liquid that was given to us in class. The other characteristics that will be looked at will be the boiling point‚ refracted index‚ and

Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper sulfate that can be added

Identifying a Salt by Creating its Heating Curve Introduction: Solubility is a substance’s ability to be dissolved in a liquid‚ usually water‚ and some substances are more soluble than others. A solution can be saturated‚ unsaturated or supersaturated. Temperature plays a large role in the solubility of substances. For example‚ on table G of the Chemistry reference tables it shows that 10g of KClO3 will dissolve in 100g of water at about 25°C‚ but at about 48°C‚ 20g will dissolve. The higher the
