Investigating pH Aim: To demonstrate dissolved carbon dioxide changing the ph level of substances. Materials: * 2 beakers * 2 straws * Stop watch * Distilled water * Lime water * Litmus Paper Method: 1. Pour 100ml of Distilled water into the first beaker‚ and label said beaker. 2. Pour 100ml of Lime water into the second‚ also Label beaker. 3. Test the two liquids with litmus paper and note the ph level‚ before any carbon dioxide has been introduced. 4. Place a straw in each

communities. This all leads to major problem of environment pollution. Idols made by non biodegradable material and toxic paints contaminate water making it unfit for survival of aquatic life and drinking purposes. The material used for idols like Plaster of Paris (POP) is mainly the compound of gypsum‚ sulphur‚ phosphorus and magnesium. Chemical paints comprise of mercury‚ cadmium‚ lead and carbon. Immersion of idols with such poisonous and toxic elements raises the level of acidity‚ solid matter

Water on Carbon Dioxide Levels Problem: How does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide? Background: This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms‚ whether it is given or released through that organism. Both plants and animals use oxygen and carbon dioxide for cellular

1. Explain how the respiratory and circulatory systems coordinate the supply and transport of oxygen to the cells and removal of carbon dioxide from the blood. (10 Marks) Paragraph 1: What happens in the respiratory system? Respiratory System: Coordinating the Supply and transport of Oxygen * Oxygen is inhaled through the nose or mouth * Travels down through the Pharynx * Travels down the Larynx * Reaches the lungs and goes through the Bronchi * Through the Bronchioles

Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

Plants can make their own food through photosynthesis and then break it down for usable energy through the process of cellular respiration. Analyze and explain how your life might be different if you could make your own food through photosynthesis. First of all if we were to be able to make our own food trough photosynthesis‚ we should have chlorophyll‚ which is the important pigment in absorbing sunlight. As an effect we will all be green in color. This may be good as there will be only one race

baking soda hit the vinegar and lemon juice‚ the balloon started to expand.Adding the lemon juice to the baking soda creates a chemical reaction. The baking soda is a base‚ while the lemon juice is an acid‚ when the two combine they create carbon dioxide (CO2). The gas rises up and escapes through the soft drink bottle‚ it doesn’t however escape the balloon‚ pushing it outwards and blowing it up. What happen when I tested the experiment was me and my mommy had test it out and I found that two of

Determining the value of molar mass of chosen compound Marta Dürrigl 1mmA Chemical reaction: b.) CaCO3 (s) + 2HCl (aq) ----------- CaCl2 (aq) + CO2 (g) + H2O(l) AIM: The aim of this investigation is to experimentally determine the molar mass of carbon dioxide (CO2) by measuring its volume and calculating its mass. CO2 which we will measure will arise as a product of a chemical reaction between Calcium Carbonate (CaCO3) and Hydrochloric acid (HCl) as it is shown in the chemical
