Keep swirling the solution until a pink color is visible throughout from the phenolphthalein. 8) If over titration occurs ask the teacher for further instruction. 9) Write down the final volume in the NaOH buret 10) Subtract the final volume of NaOH from the initial volume. 11) Repeat this process at least twice more. Materials: * Buret (50mL) * Graduated Cylinder (10mL) * Beakers (250mL) * Buret stand * Erlenmeyer flask (125mL) * Safety goggles * Buret clamp * 0.10M HCl (aq) (25.0mL) * NaOH (aq) Vocab: * Standard Solution: a solution containing a precisely known concentration *
The chemical reaction for this experiment is: 3NaHCO3(aq) + C3H4OH(COOH)3(aq) C3H4OH(COONa)3(aq) + 3H2O(l) + 3CO2(g) sodium bicarbonate + citric acid sodium citrate + water + carbon dioxide Purpose: The purpose of this lab is to show visual evidence of the law of conservation of mass during a chemical reaction. Materials: 1) Plastic beaker 2) Paper towel 3) Effervescent tablet (Alka Seltzer) 4) Access to water 5) Balance 6) Safety goggles 7) Plastic bottle (500mL) with air-tight screw cap Variables: - Dependent Variables: - Independent Variables: Procedure: 1) Pour about 50 mL of water into the beaker. If you get the outside of the beaker wet, dry it using a paper towel. 2) Break the tablet in half. Shake or blow any loose grains off the tablet.
Many people think that diet soda is healthy because diet soda only contains no fat, low or no calories and no sugar. A can of soda can provides 140 calories, whereas a can of diet soda only provides 4 calories. If we switch from a regular soda to a diet soda then we can save up to 146 calories. Therefore some healthy experts recommended to drink diet soda instead of regular soda. In a can of 12 oz diet soda, there are a total fat of 0.7g, no saturated fat, no polyunsaturated fat, no monounsaturated fat, no cholesterol, 28mg of sodium, 25mg of potassium, 0.84g carbohydrate, no dietary fibre, no sugars and 0.39g of protein.
Now refrigerate until chilled. • Add the strawberry and basil syrup to the tea and serve with crushed ice. 15. Apple Iced Tea – This is one of the most heavenly combinations that you can offer your guests. Ingredients • 1 cup apple juice • Tea bags • Boiling water • Crushed ice Instructions • Place the tea bags in the boiling water and discard them after 15 minutes • Add the apple juice and crushed ice and serve chilled with a slice of
It claimed to cure whatever bothered you such as an addition to morphine, headaches, and impotence as well as more. It is also a concentrate which is sold to its bottlers who then add water and bottle it. So Coke is older but both Pepsi and coke are over 100 years old and is just as popular now as they were then. I do not see this changing any time soon. I mean could you image not being able to buy Coca-cola or Pepsi.
Many dieters say soy milk is perfect, but nevertheless there are many others who say that almond milk is the best. My intention is to compare soy milk (vanilla) versus almond milk (vanilla) and expose the strengths and weaknesses of both in order to have a better understanding at the time of purchase. All the nutritional data I’m going to use for this comparison has been obtained through ESHA, with a control of 8oz of each product. Calorically speaking, vanilla soy milk has about 150 calories versus 90 in the vanilla almond milk. For those people that count calories, almond milk has the advantage.
4. Add 5 mL of acidified water to the “R” tube. Once added start swirling the chemicals without shaking up or down. 5. When the solution turns orange, pipet 30 drops of the colored
It’s not. To make fog in a bottle, obtain a clean 1- or 2-liter plastic soda bottle and put several spoonfuls of water in it. Cap the bottle tightly, and shake it to help the water evaporate into the air. In a minute or two, the relative humidity in the bottle will reach 100% and you’ll be ready to do the experiment. Lay the bottle on its side on the fl oor, and step on it with your shoe.
Now, take the same piece of plasticine tied with thread and immerse it into the measuring cylinder filled with water, by holding the thread. 6. Check the changes in the water level by subtracting the final volume (Current Volume) with the initial volume. 7. Record the change in water level as the volume of the piece of plasticine.
Diet Pepsi contains a zero-calorie cola beverage which is an artificial sweetener with aspartame and ace k. Diet Pepsi contains 2.92 mgs of caffeine per fluid ounce (9.86mg/100mls).The ingredients is carbonated water, caramel color, aspartame, phosphoric acid and potassium benzoate so it preserves freshness. It also includes caffeine, citric acid, natural flavor and Acesulfame potassium. The ingredients in regular Pepsi are carbonated water, high Fructose, corn syrup, caramel, color, sugar, phosphoric acid, caffeine, citric acid, natural flavor. Due to the effects of caffeine contained in the Pepsi it may cause alertness and energy. Caffeine is known for awakening the body and causing productivity.
