The curve on the graph goes flat when the reaction is complete.
Marble chips and hydrochloric acid experiment graph.
Place 40cm 3 of hydrochloric acid in an conical flask.
The rate of this reaction can be changed by changing the size of the marble chips.
Conical flask glass jam jars measuring cylinder stop clock watch with seconds stop watch app direct reading balance dilute hydrochloric acid cotton wool marble chips method.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
The essay on hydrochloric acid and marble reactions.
Hydrochloric acid marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at which the reaction between marble chips caco and hydrochloric acid hcl takes place.
There are many variables that affect.
Draw a curve of best fit.
Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung.
Calcium chloride solution is also formed.
Dgfhhdhdinvestigating rates of reaction aim the aim of my investigation is to find out how rates of reaction are affected by temperature specifically how the rate of the reaction between hydrochloric acid and marble chips is affected by the temperature of the hydrochloric acid.
An investigation of the reaction between marble chips and hydrochloric acid.
For each concentration of hydrochloric acid plot a graph to show.
The graph which is most likely to.
To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials.
In the reaction between calcium carbonate marble chips and hydrochloric acid we can use the apparatus below to find the rate of reaction.
Volume of gas cm 3 on the vertical axis.
Time s on the horizontal axis.
This is because as time goes on the volume of the gas evolved does not change.
The graph which is most likely to be produced from experiment 3 is graph a the only difference in the conditions compared with experiment 1 is that there is twice as much acid.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
This will not make any difference to the graph as it is the marble chips that are used up not the acid so the graph will be the same.
Measuring the rate of loss of a gaseous product.
