Mixture Lab

During the Mixed Substances lab the objective was to see how many properties of individual substances compare with properties of mixed substances. From here on the words that would help you along the way of the lab for your research is mixture, homogeneous mixture, and last but least heterogeneous mixture. The hypothesis or guess on what would happen when the water is mixed with the cornstarch, is the cornstarch and water will mix and form a new liquid/solid. However, the Investigating Mixtures lab objective was to observe that not all liquids behave the same way when mixed with other liquids. Moreover the hypothesis of this experiment was that the vegetable oil and colored will separate because the vegetable oil will go to the top and the

The second question asked was, “Describe how the new mixture is different from the original substances?” The new mixture that was created is different from the original substances because when you would touch the mixture is was a chalky feeling liquid and when you wouldn’t touch it at all it was a solid. From the original substances to the new mixture the cornstarch was very soft and felt like powder sugar and the water was so clear that you could see through it. The third question that was asked was, “Was the new mixture made from a physical change or chemical change? How do you know?” The new mixture that was created was a chemical change because it changed the substance and it now has new

The very first question that was asked was, “ Does water mix with food coloring? What evidence supports your answer?” When you would add the food coloring to the water it would mix because the water would turn blue. The second question that was asked was, “Does water mix with vegetable oil? What evidence supports your answer?” Water and vegetable oil don’t mix because the oil is less dense than the water and the oil will go on the top of the water. The third question that was asked was, “What happened when you turned the container upside-down?” When we turned the container upside-down, the oil and water stayed separated with many bubbles but switched spots. The fourth question that was asked was, “Which has a higher density? Water or vegetable oil? Explain?” The water has a higher density because the water is 1.00 g/cm3and the oil is is 0.92 g/cm3.The fifth question that was asked was, “Describe what you think will occur if droplets of soap was added to the mixture of water and vegetable oil? Why?” If we were to add droplets of soap to the mixture of the water and vegetable the outcome would change because soap has a different density than the other substances. The sixth question that was asked was, “Was the mixture a homogeneous or heterogeneous mixture? Explain?” The mixture is a homogeneous mixture because you can’t see all the parts of the substances
