Cations I found out what Cations where present by doing a flame test. When I put my substance in the Bunsen burner I got a bright yellow colour which means that the Cation for my substance was sodium ions. Anions To find the Anions I had to go through a series of tests to find out which Anion was present. From all the tests I found out that the test for bromine halide worked and the test for sulphate also worked. Conclusion In conclusion I found out that the ions present in my sample where

In This POW‚ our task was to find out how Carletta‚ a highly intelligent and very talkative student solved her wise teacher’s problem. She and two other students were complaining about the number of POW’s that they have had to complete throughout the semester. The teacher and the three students made a deal. The three complaining students would close their eyes and sit down in chairs. While they were sitting down‚ the teacher would take three hats out of a possible five‚ (3 blue hats and 2 red hats)

Starch Diffusion in a Caterpillar’s Digestive Tract The object of this particular experiment is to gain knowledge on diffusion across a plasma membrane‚ which is selectively permeable. Diffusion is the movement of a substance from a region of high concentration to lower concentration. Experiment 2 was performed to see how the substance’s‚ starch‚ and diffusion process across a plasma membrane is affected by amylase. We prepared a simulated digestive tract of a caterpillar‚ as the plasma membrane

eight years of age and 40 were adults between 20 to 40 years old. All participants reported having no problem related to anomalous colour perception‚ and had normal or corrected-to-normal visual acuity. Materials Before Stroop task‚ Ishihara’s (1939) test of colour blindness was used to check the colour vision of each subject. The Stroop task was presented on a Macbook Air with 13.3-inch (1440 x 900) and Intel HD Graphics 5000 1536 MB. E-prime 2.0.1 was used for formulating the Stroop task. Response

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are

Bread contains starch. The starch content in bread is derived from the starchy endosperm of wheat. Refined breads have the bran and germ removed from the wheat in order to produce softer‚ silkier flour. there is a lot more food containing starch like: Starchy foods such as potatoes‚ bread‚ cereals‚ rice and pasta should make up about a third of the food you eat. Where you can‚ choose wholegrain varieties‚ or eat potatoes with their skins on for more fibre. Starch is the most common form of

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of
