Solubility equilibrium

What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

Emulsions are two-phase systems, a mixture of two or more liquids that are normally immiscible. There are two phases in the system, in which one is the continuous phase and the other one is the dispersed phase. Types of emulsions [38] Oil in water (o/w): in which oil is the dispersed phase and water is the continuous phase. Water in oil (w/o): in which water is the dispersed phase and oil is the continuous phase. Emulsions have a cloudy or opaque appearance because particles scatter light…

Describe the Properties of Biopol Biopol is a copolymer made of the monomers PHV and PHB. PHB alone, with its short methyl side chain, is brittle and has very high crystallinity, meaning it cracks easily. Due to its high crystallinity and overall unsuitable properties for industrial use, PHV has been added to created PHBV, or Biopol. Biopol is semicrystalline, meaning it can still crystallize as well as melting at a lower temperature than PHB, making it industrially suitable. Due to its long…

A important tests were performed on the product to pressure the results: melting point value, percent yield, IR, and TLC. The experimental melting point value was found to be a range of 165-167 ºC being a little lower than the literature value for camphor, the intended product, was 175 ºC. The sharp range was resulted in a slightly pure product. The percent yield was lower than expected which can be the reason most of the product was lost during the extraction and almost completely sublimated…

Conclusion: I predicted that liquid A was glycerine due to a calculated density of 1.38 g/mL. However I was wrong the actual density of liquid A was 1.38 g/mL and the substance was actually corn syrup. Therefore the percent of error for the density of liquid is 1%. For liquid B I had predicted that its substance would be Glycerine due to the calculated density of 1.19 g/mL. I was incorrect for the density of liquid B which was actually 1.26 g/mL, but because the calculated and actual densities…

charged ions are separated, by altering the pH of the solution; which shifts the equilibrium of the molecules. During this lab we will separate two compounds from one solute that will be formed by amalgamating a ‘slurry’ – provided by the instructor. Resin or cellulose is used to create a sound support unit in order maintain a constant positive or negative charge respectively, this will allow separation to occur when equilibrium is shifted during the reaction. The column will have a support unit…

Extraction was the main method of removing compounds from the sample. The component X was removed from the sample by first adding the organic solvent dichloromethane to the test tube. After aggravation, the component X dissolved into the solvent. Since components Y and Z were insoluble in the organic solvent they remained as solids. The test tube was then placed into a centrifuge and ran for thirty seconds. By doing so, the unsettled solid were forced to accumulate at the bottom of the test tube…

Nanocrystals (NCs) are interesting material, as their electrical and optical properties can be tuned by tuning their size or surface area. They have diverse applications in electrical devices. Nanocrystal thin film transistors (NC TFTs) have been intensively researched, because of their low-temperature processability.1,2 Colloidal NCs are synthesized in a liquid solution containing some stabilizing organic molecules, broadly termed as surfactants, which are bulky and insulating ligands. The…

Investigating if dissimilar sized candles have the capability of drinking equivalent quantity of water. Aim: The drinking candle science experiment is quite enthralling, as when performed, you'll observe a burning candle drinking up all the water kept beneath it due to the behaviour of the atmospheric pressure. The aim of this experiment is to investigate if unlike sized candles have the capability of drinking the same amount of water. Hypothesis: With all the information given on different…
