What are the minerals in rainwater?
Rainwater is a mixed electrolyte that contains varying amounts of major and minor ions.
Sodium, potassium, magnesium, calcium, chloride, bicarbonate, and sulfate ions are major constituents, to- gether with ammonia, nitrate, nitrite, nitrogen, and other nitroge- nous compounds (Hutchinson, 1957)..
What nutrients does rainwater have?
Rain contains nitrates—an important macro-nutrient. Rainwater contains nitrate – the most bio-available form of nitrogen. Nitrogen is one of the three key macro-nutrients that plants need to thrive–necessary for the development of lush foliage. Many forms of nitrogen are not actually absorbable by plants.
Is rain water same as distilled water?
This is because rainwater is pure, distilled water evaporated from the sun – nothing else. However, when rainwater falls from the sky, substances from the air and land melt into the rainwater. Fortunately, when rainwater soaks into the ground, it then becomes mineral water.
Does rain water contain vitamins?
Rain water contains Vitamin B12. Many microorganisms that occur naturally in nature produce Vitamin B12 and as rainwater falls through the air, these microorganisms get caught up inside it & produce Vitamin B12 as a metabolic by-product.
Is rain water a mineral?
Rainwater is slightly acidic and very low in dissolved minerals; as such, it is relatively aggressive. … Rainwater lacks minerals, but some minerals, such as calcium, magnesium, iron and fluoride, in appropriate concentrations are considered very essential for health.
What is the pH of the rainwater?
between 5.0 and 5.5Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
