They are detected by chemical methods of analysis as spectrophotometry, ion specific electrodes, titrimetry, etc.
The hardness of water depends primarily on the concentration and chemical identities of the metal cations dissolved in the water. The non metal ions dissolved in the water have little effect unless the particular ions are capable of forming coordinate covalent bonds to the metal ions.
The pH of water changes after a reaction with an alkali metal because the metal reacts with water to produce hydroxide ions, increasing the concentration of hydroxide ions in the solution and making it more basic. This leads to a shift in the pH towards the alkaline side of the pH scale.
Large sources of water polluted by high concentrations of ions include saline lakes, such as the Great Salt Lake, and industrial wastewater discharges that introduce heavy metals and other ions into rivers and oceans. Agricultural runoff can also contribute to ion pollution, particularly through fertilizers that increase nitrate and phosphate levels in nearby water bodies. Additionally, mining operations can leach heavy metals and other ions into groundwater and surface water, further degrading water quality.
When a metallic salt is dissolved in water, the metal ions present in the salt become hydrated and surrounded by water molecules. When this solution is placed in a hot flame, the water evaporates due to the heat, leaving behind the metal ions. The metal ions then absorb the energy from the flame and get excited, leading to the emission of characteristic colors in the flame test.
EDTA is sparingly soluble in water because it forms complexes with metal ions, reducing its solubility. The formation of strong metal-EDTA complexes makes it challenging for EDTA to dissolve in water because it ties up with metal ions in solution.

Highly polluted water with acid typically has a pH below 6.5. Acidic water can have a pH ranging from 0 to 6.5, indicating a high concentration of hydrogen ions.
No, a base is a substance that raises pH when added to water. While some bases do indeed release metal and nonmetal ions, many do not, and many that release metal/nonmetal ions are not bases.

Yes, EDTA (Ethylenediaminetetraacetic acid) is water soluble. It forms stable complexes with metal ions in water due to its ability to chelate metal ions.
The metal cations are responsible for making water hard. Examples of these cations includes the calcium ions, the magnesium ions, the aluminum ions, and the manganese ions.

Nitrates are commonly used as sources of metal ions because they are water-soluble and can easily dissociate into metal cations and nitrate anions in solution. This allows for easy separation and purification of the metal ions during various chemical processes. Additionally, nitrates are generally stable compounds that do not decompose easily, making them convenient sources of metal ions for laboratory and industrial applications.
Metal ions in effluents can be toxic to aquatic organisms and can accumulate in the environment, leading to long-term negative impacts on ecosystems. Removing metal ions helps prevent water pollution, protects aquatic life, and ensures the safety of water resources for human consumption and recreational use.
Tomato juice in a typical tomato fruit contains acid. Well, take it as vitamin C aka Ascorbic acid. We are aware that the condition that a metal rusts is when it is exposed to air ( mainly oxygen ) and water. There are conditions where metal rusts at faster rate. For instance, when metal come upon contact with an acid or salt water. Here is what happens. When the acid in tomato come upon contact with metal, a chemical reaction takes place. This happens as metal begins to react with the acid to form salt and hydrogen gas. Part of the metal that remains become more affected as the condition surrounding it is optimum for rusting of metal to occur. The metal is oxidized into metal ion while the water (in tomato juice contains hydroxide ion) will dissociates into becoming hydrogen ions and hydroxide ions. The hydroxide ions receives the electron donated by the metal to become oxygen gas. When there is the presence of both ions ( metal ions and hydroxide ions ) the ions combines to form metal hydroxide which will later dehydrate into rusts.
