Rates of reaction - marble chips and hcl in this experiment, marble chips, or calcium carbonate (caco3), will be dropped into a flask containing hydrochloric acid (hcl. Measuring the rate of a reaction by collecting gas - marble chips and hydrochloric acid crash course chemistry #37 - duration: 6 chemical reactions that changed history - duration:. Page 2 q1marble chips are mainly calcium carbonate (caco 3) a student investigated the rate of reaction between marble chips and hydrochloric acid (hcl.
An experiment to investigate the rate of reaction between marble chips and hydrochloric acid analysis from my graph i can see that as the concentration of hydrochloric acid increased as did the rate of reaction. Marble is calcium carbonate and thus behaves in the same way: caco3 (s) + 2hcl (aq) cacl2 (aq) + h2o (l) +co2 (g) in this experiment, i am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. 3 cm of magnesium ribbon typically has a mass of 004 g and yields 40 cm 3 of hydrogen when reacted with excess acid 50 cm 3 of 1m hydrochloric acid is a six-fold excess of acid in this reaction, the magnesium and acid are gradually used up.
What is the reaction of hydrochloric acid and marble chips often used to demonstrate the effect of increasing the surface area of a solid 1 of 7 what do you do first with the reaction of hydrochloric acid and marble chips experiment (1) 1) measure the volume of gas evolved with a gas syrine and. Investigation into the effect of one factor on the rate of reaction using a gas collection method investigation into the effect of one factor on the rate of reaction between dilute hydrochloric acid and sodium thiosulfate investigation into the effect of various catalysts on the decomposition of hydrogen peroxide. Rate of reaction experiment 1 weight on pan rate of reaction means the speed of the reactiontime balance loss of mass this can be either: 0 50 (a)the rate of disappearance of reactants 1 4993 007 (b)the rate of appearance of products 2 3 the rate of reaction between marble chips and dilute 4 hydroochloric acid can be tracked by measuring the 5 weight loss as the reaction proceeds. Planning i will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction i will use concentrations of 50cm3 using different volumes of water and acid. We can investigate the effect of surface area on reaction rate by looking at the reaction between marble chips and dilute hydrochloric acid an acid is a substance that forms a solution with a ph value of less than 7.
The purpose of this experiment is to discover the reaction rate in which acid rain weathers marble statues, or in our case, marble chips the different concentrations of diluted water mixed with hydrochloric acid the mass of the marble chips in each test tube to ensure it is a fair test the. Factors affecting the rate of reaction experiment 1 the rate of reaction using large marble chips procedure 32 mol dm-3 hydrochloric acid is added to the marble chips 50 cm3 of 0 the stopwatch is started simultaneously. Describe an experiment to show the effect of surface area on the rate of the reaction a flask is stoppered with cotton wool and contains marble chips the cotton wool is to allow the carbon dioxide to escape, but to stop any acid spraying out. The rate of reaction between the marble chip and hydrochloric acid is moderately high the rate of reaction between lead(ii) nitrate solution and hydrochloric acid is the highest. Concentration (of hydrochloric acid) 3 surface area (of marble chips) 4 a catalyst however instead of investigating all four variables, i have chosen to investigate how different concentrations of hydrochloric acid affect the rate of reaction between marble chips and hydrochloric acid.
You are going to collect and analyse data to find the order of this reaction with respect to hydrochloric acid. ‡marble chips and the carbonates are stored in the general chemical storage cabinets hydrochloric acid is stored in the cabinet under the hood on the right. • 3m hydrochloric acid with small marble chips a reading was taken initially every 15 seconds for a minute and then every 30 seconds for the next 4 minutes.
The rate as count /sec use the first part of the results to find the rate eg over 1 - 2 minutes plot on paper a graph of rate vs grade size of the marble chips (grade size on the horizontal axis and. Marble chips and hydrochloric acid concentration if there are more particles, more collisions take place this is similar to having a tank of fish - if there are many fish, the fish will swim into one another. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. In doing rate experiments with a solid and solution reactant eg marble chips-acid solution or a solid catalyst like manganese(iv) oxide catalysing the decomposition of hydrogen peroxide solution, it is sometimes forgotten that stirring the mixture is an important rate factor.
Coursework - rates of reaction research the rate of reaction tells us how quickly a chemical reaction takes place it is important for people in industry to know how fast a reaction goes they have to know exactly how much of their p. 3 rates of reactions science (chemistry) coursework my coursework is based on rates of reaction this deals with the time taken for reactants to be changed into products, when the variables are altered and analysed. Marble chips (calcium carbonate) were added to hydrochloric acid in a conical flask the mass and size of marble chips, and the concentration and volume of hydrochloric acid used, were the same for both.
