    report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through displacement

    is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration is called

    Experiment 2: Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins

    Determining the percent Concentration of a given Solution using Titration Morphy Kuffour Mrs. Langlis‚ AP Chemistry C-D 9/24/2017 Purpose: Determining the precise concentration of vinegar through titration using a standard solution of Potassium Hydroxide (KOH) (aq) Background: Vinegar is a solution of acetic acid (CH3COOH) in water. The concentration of acetic acid in Vinegar is written as a Molarity (mol/L). In this experiment‚ titration is used to determine the concentration of acetic acid in vinegar

    The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

    with thiosulfate solution‚”2 being the difference from the former type of iodine titration. Iodometry is more widely used‚ as in this experiment‚ because there are only a few strong reducing agents; thus few iodometric determinations. (2) As mentioned earlier‚ iodometry involves the oxidation of iodide ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution. (2) For example

    The Effect of Concentration Gradient on Osmosis Abstract: Osmosis is the passive movement of water from an area of higher concentration to an area of lower concentration‚ usually across a membrane (Thorpe 2013). Tonicity is the ability of a solution surrounding a cell to gain or lose water (Reece 2011). There are many factors that affect the rate of osmosis. These include temperature‚ surface area‚ difference in water potential‚ pressure‚ light and dark and most importantly what we will be talking

    Extraction The first stage of processing is the extraction of the cane juice. In many factories the cane is crushed in a series of large roller mills: similar to a mangle [wringer] which was used to squeeze the water out of clean washing a century ago. The sweet juice comes gushing out and the cane fiber is carried away for use in the boilers. In other factories a diffuser is used as is described for beet sugar manufacture. Either way the juice is pretty dirty: the soil from the fields‚ some small
