The variables that i shall be changing will be the concentration of hydrochloric acid and water.
Marble chips and hydrochloric acid.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
An investigation into how changing one variable influences the rate of reaction between marble chips and dilute hydrochloric acid planning section when dilute hydrochloric acid reacts with marble chips the following reactions occurs.
Caco3 2hcl h2o co2 this is the reaction we will be investigating.
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.
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.
A tube to connect the conical flask to the measuring cylinder.
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.
This is due to the collision theory.
With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.
The rate of this reaction can be changed by changing the size of the marble chips.
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.
In high concentrated acid the particles of the marble chip will move faster due to the more collisions between the particles of marble chips and the acid.
Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
This process is based on random particle movement.
I predict the higher the concentration of hydrochloric acid faster the reaction rate and more carbon dioxide will be produced as the time increases.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
There are many variables that affect.
