If the mixture still contained un-dissolved borax‚ mixture was taken off the hotplate. b. If the mixture of borax was completely dissolved‚ more borax was required to be added to the mixture until some borax remained un-dissolved at 65*C. 6) After allowing the borax mixture to heat to 65*C‚

M11G Title : Determination of Chloride in Urine in Different Circumstances Aim: To determine the chloride content by titrating mixtures of urine against potassium thiocyanate under in different circumstances. Research Question: How do different conditions of urine samples collected affect its concentration of chloride which is measured by titrating the mixture of urine with potassium thiocyanate until it turns red? Hypothesis: The greater the consumption of food‚ the higher the chloride

Separation of a Mixture of Solids Purpose: The purpose of this experiment was to help the student learn how to separate a mixture of multiple different solids and determine the percentage of each component of the mixture. Procedure: I started off by removing the iron using the magnet‚ and then I weighed all of the iron I obtained from the mixture in a container I already knew the weight of and calculated the net weight of the iron. Next‚ I took the remaining contents of the mixture and added

Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a substance

distillates based on the temperatures at which they boil. Liquids with higher volatility boil at lower rates than liquids that are less volatile. Because of this when a mixture of two substances is created there will be a spike in the boiling point. At the spike the more volatile substance has vaporized and condense out of the mixture leaving the less volatile liquid. Thus the temperature has to increase or spike to boil the remaining substance. In the case of toluene and cyclohexane‚ cyclohexane is

method for purifying and separating mixtures of liquids into their individual components. As the mixture is heated‚ the temperature rises until it reaches the temperature of the lowest boiling substance in the mixture‚ while the other components of the mixture remain in their original phase in the mixture. The resultant hot vapor passes into a condenser and is converted to the liquid‚ which is then collected in a receiver flask. The other components of the mixture remain in their original phase until

The mixture was poured into the filtering equipment until all liquid (whey) was separated from the curds. 7. The way was then poured into the sink. 8. Curds were then put back into their original beaker and one spatula of baking soda was put into the mixture. 9. The mixture was stirred
