PREDICTION When the concentration of acid increases, more gas will be given off faster. This page uses the reaction between marble chips and dilute hydrochloric acid to investigate the relationship between the rate of reaction and the surface area of the marble chips. surface area and therefore has the fastest reaction rate. We only filled it up 3/4 of the way because otherwise the water displaced into the bowl during the experiment would cause it to overflow onto the floor and work surfaces. This is why a catalyst is often used in the form of a powder. Method: Add Hydrochloric Acid into a conical flask; Use a capillary tube to connect this flask to a measuring cylinder upside down in a … I shall start by filling up a measuring cylinder with water and putting it in a water bath so I can record how much gas has been given off. This would create a safety hazard, maybe causing slipping. I will weigh out one gram of marble chips using a balance and put it in a conical flask and add to it a concentration of 50cm3 using water and hydrochloric acid. HCl + calcium carbonate calcium chloride + carbon dioxide + water. To observe the effect of a catalyst (Manganese Oxide) on the rate of decomposition of Hydrogen Peroxide. Professor Harris. Surface area: add different sizes of marble chips (solid, crushed and powder ) Concentration: add different concentrations of Hydrochloric Acid. I shall start by filling up a measuring cylinder with water and putting it in a water bath so I can record how much gas has been given off. Verified writer. 4.9 (457) Ramielle. It uses a video which lets you see a commonly done experiment as it happens in the lab, and allows you to record and process your own results if you want to. Top writers. Weigh 5g of caco3 chips and remove the weight boat from the scales 3.2 Place a 250ml beaker on … Method I will weigh out one gram of marble chips using a balance and put it in a conical flask and add to it a concentration of 50cm3 using water and hydrochloric acid. I know this from my trial experiments. 3.1 Place a weight boat on the scale and tare it. In the reaction between calcium carbonate and dilute hydrochloric acid, calcium carbonate may be used in the form of marble chips. 3b.To observe the effect of surface area (particle size) on the rate of reaction between magnesium ribbon and hydrochloric acid. Method The first thing that we did was fill the plastic bowl with water. Verified writer. To observe the effect of surface area (particle size) on the rate of reaction between marble chips (calcium carbonate) and HCl. 4. Rates of Reaction: Marble Chips and Hydrochloric Acid Rates of Reaction PLANNING AIM To find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid. Then we weighed out the marble chips. Method. Hydrochloric acid (1ML) Marble chips (5g) Powder (5g) Stopwatch Conical Flask Scales Spatula Measuring cylinder Beaker (250 ml) Gloves Apron Goggles Thermometer Weight boat 4.1 Methodology The equipment was set up as shown in the diagram above .
