To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials.
Marble chips and hydrochloric acid experiment equation.
Marble chips placed onto pieces of paper.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
3m hydrochloric acid with large marble chips 1 5m hydrochloric acid with small marble chips 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.
This process is based on random particle movement.
2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.
Measured out 1ml of water in a 10ml measuring cylinder and placed into the test tube labelled 2.
Hcl calcium carbonate calcium chloride carbon dioxide water.
In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Marble chips and hydrochloric acid 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.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
This was done as the first trial showed that in the first 2 minutes the.
Calcium chloride solution is also formed.
Plugged in scientific scales and weighed out 1g of marble chips for each test tube.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
An investigation of the reaction between marble chips and hydrochloric acid.
Place 40cm 3 of hydrochloric acid in an conical flask.
Measured 5ml of hydrochloric acid in the 10ml measuring cylinders and placed into each beaker separately.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
There are many variables that affect.
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.
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.
With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.
