Chemistry the acidic environment assignment

The two indicators which satisfy this are litmus Chemistry the acidic environment assignment methyl orange. When a system in equilibrium is disturbed, the system adjusts itself to counteract the change and establish a new equilibrium.

By testing soil, the types of plants or crops that will grow in it and soil conditioners required can be determined.

If the quantity of acid rain is greater than the capacity of an environment to neutralise it then the following can occur: Identify acids including acetic ethanoiccitric 2-hydroxypropane-1,2,3-tricarboxylichydrochloric and sulfuric acid.

As a general rule, acids and bases can be identified by their properties Acids: Non-metal oxides and semi-metals Conditions under which they present acidic properties: Pressure of a system — in a reaction involving only gases: Adding a catalyst lowers the activation energy for both the forward and reverse reactions.

Conversely, decreasing pressure will cause the equilibrium to shift in the direction with the most number of gas molecules. Action of sunlight on NO and O2 NO2 Industrial Combustion of fossil fuels coal often contains some S Smelting of copper, zinc and lead sulphides High temperature combustion of fuels in vehicles and power stations With reactions involving multiple states, the fact that solids and liquids take up much less volume than gases hence having less effect on pressure must be considered.

Testing pH of soil Most plants have a preferred soil pH range, which is important particularly in agriculture. Achieved HSC Mark of 94 with these notes.

Consider the equilibrium reaction below: There is no current evidence for a global increase in the concentrations of sulphu Ozone can reduce the lung capacity of humans, with severe effects on asthma sufferers.

For example, if [A] is decreased then the above equilibrium will shift to the left. Assess the evidence which indicates increases in atmospheric concentration of oxides of sulfur and nitrogen. The amount of release of these oxides has been far greater since the industrial revolution due to increased burning of fossil fuels.

The new equilibrium that is established is different to the original — the position of the equilibrium is said to have shifted. In this reaction increasing heat causes the reaction to shift in a way that reduces excess heat — in the direction of the endothermic reverse reaction.

Example 1A number of indicators are used to test a solution: These can then be used to checkout other documents on Thinkswap. Reaction with acids to form salts and usually water: Acidity increases up the group. That is, the reaction will shift to the left.

Steam locomotives, the major machines of the Industrial Revolution, used coal as a fuel source and thus increased the amount of sulphur dioxide. Sulfur Dioxide and the oxides of Nitrogen natural and industrial sources Atmospheric oxides are formed from natural and man-made sources: Distilled water in contact with the atmosphere has a pH of 5.
