Journal 5

In todays lesson we learnt about Acids and Metals. We also did a prac on this topic. The aim of this prac was to observe  the reaction of an acid with a metal. In this practical we had to also find out what was the gas that was being formed. The gas was hydrogen.

Some of the things that we learnt during the lesson were:

• Acids contain the element hydrogen in combination with other non metal elements.
• Some of the properties of acids: acids have sour taste, acids turn blue litmus red, acids conduct electricity in aqueous (water) solution.
• When an acid reacts with a metal, hydrogen gas and salt are produced.
• A salt is an ionic compund containing the ions left over after reactions.
