It is clear that salt‚ also known as sodium chloride‚ should no longer be used on our roads in the winter months. The first two reasons why salt needs to stop being used are because salt negatively affects aquatic ecosystems and causes damage to vegetation. The third reason is because thankfully‚ there are alternatives that we can use‚ that would be benefiting us which we should use instead of sodium chloride. To begin with‚ sodium chloride is detrimental to our aquatic ecosystems when it is

Experiment 11 Date: 28-3-2011 Title: Interpretation of reaction by the Le Chatelier’s principle Objective: To determine the factors that affecting the equilibrium position Introduction: Le Chatelier’s principle states that if a system in equilibrium is subjected to a change‚ the equilibrium position of the system will shift in a direction to minimize the effect of the change. Iron(III) ions and thiocyanate ions (NCS-) react in solution to produce thiocyanatoiron(III) (FeNCS2+)‚ a
