The minerals dissolved in water amount to 2.79 grams per liter.
During this process mineral of the protolith partially dissolve, diffuse through the water and precipitate elsewhere.
However, in some cases a certain mineral dissolves and not precipitate again.
Many minerals, however, mutually dissolve into solid solutions, such that a single rock is a uniform substance despite being a 'mixture'.
When the minerals dissolve in water, they form a measurable solution called "total dissolved solids."
Rain water and snow from the mountains go deep into the earth, where the water is heated and the minerals dissolve.
Many minerals and gases will readily dissolve in water.
The second reason for concern is for animals that rely on calcium carbonate for skeletal elements, as this mineral will dissolve in acidic media.
The mineral dissolves slowly in water and quickly in cold, dilute hydrochloric acid.
The mineral is insoluble in cold acids, such as HCl, but dissolves upon heating.
