Acid Rain Lab #1 Chem. 1 20 February 2016 Concordia University Texas Angelina Luna angelinaluna97@yahoo.com Chem 1- Sect C Acid Rain Lab #1 Professor Koeck Abstract In this experiment our main objective was to create three gaseous oxides CO₂‚ SO₂ and NO₂ by using data that was collected using a pH sensor which was connected to a laptop with LoggerPro and Vernier. We created the gases by bubbling each gas into the water to create the three acidic solutions we were looking for. Once that

Acetic acid‚ a pungent smelling colourless liquid having sour taste‚ used very commonly in the chemistry laboratories. It got its name from Latin word Acetum‚ which means vinegar. Pure acetic acid is also called glacial acetic acid‚ because in winters it freezes easily as temperature goes below 16-17°C. Therefore it looks like as if a small glacier is there in the bottle‚ hence called glacial acetic acid. Laboratory and daily life uses of acetic acid are: (i) Acetic acid is used in household kitchens

other units exist. The equation for baking soda and vinegar is CH3 COOH + Na HCO3 -> CH3 COONa + H2CO3 . This equation effects pressure and volume by rising the temperature and wanting to get out of the object. The researchers hypothesis is that when the volume decreases the temperature rises and the object inflates because it wants more space. II. Materials Baking soda Vinegar Zip lock bag String III.

Lab Report Acids and Alkalis: Chemistry of Neutralization and Salt Formation Introduction: An acid is a group of chemicals. Acids are positively charged ions‚ they are liquid and are solutions of pure compounds in water. If you want to know if something is an acid‚ you can test it by using litmus paper. Acids will turn litmus paper red‚ whilst alkalis will turn it blue. Alkalis are negatively charged ions and are usually solid. Aim: To find out how much of different acids is needed to neutralize

effects that acid rain has or does not have on seed growth and germination. The observation gathered from this experiment was that regular rain water that has a neutral pH is a better solution for seed growth. The seeds that were watered with the well water prospered more than the ones grown in the lemon juice solution. The results from this experiment were a little confusing‚ because in the first trial the seeds watered with well water germinated more than the seeds watered with the acid rain solution

Kong Acid rain on plant -Background information Unpolluted rain is normally slightly acidic‚ with a pH of 5.6. Carbon dioxide (CO2) from the atmosphere dissolves to form carbonic acid. Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition‚ which can appear in many forms. Wet deposition is rain‚ sleet‚ snow‚ or fog that has become more acidic than normal. Dry deposition is another form of acid deposition‚ and this is

(Fe3+ ) form. Ferric form is not usually absorbed in the body. In the stomach‚ there is low pH of 2 due to presence of gastric acids such as Hydrochloric and Ascorbic acids. These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid ‚ the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+

Abstract: ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First‚ the base was created‚ which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that‚ one

When the experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that
