Density Column What is density? We will be working with many different liquids. Each of the liquids has a different‚ characteristic density. One way to think about density is how thick or heavy an object is. The liquids with lighter densities will float. The liquids with heavier densities will drop to the bottom. You may have noticed that sometimes‚ liquids mix together – this is because the chemicals dissolve in each other. During our experiment‚ the liquids will stay separate because we will

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

Look at these pictures. Label them as solid‚ liquid or gas. Use them to help you cross out the wrong information in the table below so you are left with only the correct information. solid liquid gas Extension: Using your table above‚ explain the following a) Why does a solid have a fixed shape? A solid has a fixed shape because the particles are very close together and arranged in strong regular lines although they vibrate the particles are so packed together

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they
