Sulphates are indicators of acid rain and can be associated with various pollutants, primarily from industrial processes and vehicle emissions. They often result from the oxidation of sulfur dioxide (SO₂) in the atmosphere, which originates from burning fossil fuels. High levels of sulphates can indicate the presence of air pollution and its potential impact on ecosystems, water quality, and human health. Monitoring sulphate levels helps assess the effectiveness of pollution control measures and environmental regulations.
Rain water does contain salts but not those which are found in sea water. Rain contains salts which are usually obtained from atmospheric pollutants such as nitrates, sulphates, and so on.
Substances which are reacted with Sulphuric acid tend to produce sulphates.
Living indicators, such as certain species of plants and aquatic organisms, measure pollutants by responding to changes in their environment. For example, some plants may exhibit stunted growth or discoloration in response to soil contaminants, while aquatic organisms can show altered behavior or reproductive patterns in polluted water. These biological responses provide insights into the level and impact of pollutants, allowing for effective environmental monitoring and assessment. By studying these indicators, scientists can gauge ecosystem health and identify areas needing remediation.

The solubility of Group 1 sulphates generally increases down the group, as the ionic size increases, leading to weaker ionic bonding. In contrast, the solubility of Group 2 sulphates decreases as you move down the group due to the increased lattice energy resulting from higher charge density and stronger ionic bonding.

Sulphates can affect people, particularly those who are sensitive or allergic to them. They may experience symptoms like skin irritation, respiratory issues, or digestive problems when exposed to sulphates in certain products such as cosmetics, medications, or food additives. It's important for individuals with sensitivities to avoid products containing sulphates and consult a healthcare professional if needed.
Hydrochloric acid (HCl) is used in the limit test of sulphates because it helps in the precipitation of sulphates as insoluble barium sulphate (BaSO4). This makes it easier to quantitatively determine the amount of sulphate present in a sample through gravimetric analysis. The addition of excess HCl ensures that all sulphates are converted to BaSO4, allowing for accurate measurement.
Indicators of good water quality include clarity, odorlessness, absence of floating debris or pollutants, and a balanced pH level. Additionally, the presence of diverse aquatic life and the ability to support recreational activities suggest good water quality.
Litchen is a dual organism which is made up of fungus and alga, Associated in a mutually beneficial association. Litchen grows where there are some pollutants. Sometime also referred to as pollution indicators. They survive on presence of pollutants, more the pollutant more the litchen and vice versa.
