Compare The Rate Of Reaction Between Magnesium And Hydrochloric Acid
1.0 Introduction
1.1 Background Information
Acids are separated into different categories. These categories are strong acids and weak acids. Hydrochloric and Sulphuric acid are strong acids, and Phosphoric acid is a weak acid. When an acid is placed into water, it ionises (Tinnesand, n.d.). Ionisation occurs when the acid splits up into its two base components. So when Hydrochloric acid is placed into water, it splits into a hydrogen ion and a chlorine ion. The amount that an acid ionises depends on its strength (Tinnesand, n.d.). A strong acid ionises completely while a weak acid only ionises partially. Furthermore, the strength of the acid will also have an effect on the rate of the reaction. A strong acid will have a faster reaction then …show more content…
1.5 Hypothesis
If the number of hydrogen atoms in an atom increases and it is a strong acid then the rate of hydrogen gas production will increase.
1.6 Justification of Hypothesis
When placed in a solution strong acids are fully ionised but weak acids are only partly ionised. 2.0 Methods
2.1 Materials
• Test tube rack
• Large test tube
• Micro test tube
• 10mm measuring cylinder
• Stirring rod
• Stop watch
• Bunsen burner
• Piece of Magnesium
• Sand paper
• Permanent marker
2.2 Diagram / Photograph 2.3 Procedure
Firstly an aim and hypothesis were written up, then 2mm of water was poured into the measuring cylinder and that was tipped into the micro tube. Then The 2mm line was labelled with the permanent market. That water was then discarded. After this the piece of magnesium was cleaned with sandpaper and bent into shape. The acid was then poured into the micro test tube, approximately 1cm from the top. The bent piece of magnesium was then place on top of the test tube. After this the large test tube was placed over the micro test tube and flipped using the stirring
