2. What are the precipitates from the mineral solutions? 3. Why is the saline solution important?

Solution

2) When the liquid in a solution evaporates and remaining solids from minerals is called Precipitation.

This is done either by cementing broken pieces of pre-existing rocks together (e.g. sandstone) or
by precipitation of minerals out of water solution (e.g. limestone)

The precipitates of minerals that form when water evaporates, leaving these minerals behind that very intense in terminal lakes like the great salt lake and the dead sea.High amounts of evaporation leave dissolved ions of gypsum.when the liquid reaches the saturation limit, the excess of salt will sink to the bottom and form a salt precipitation.

3) The solution of sodium chloride (table salt) in water is called saline solution.

It is 0.9% Sodium Chloride or Normal Saline Solution In medicine, normal saline (NS) is the commonly-used term for a solution of 0.9% w/v of NaCl.  

Importance:

Saline solutions are available in various formulations for different purposes. Salines are also used in cell biology, molecular biology and biochemistry experiments.It maintain a balance of osmotic pressure between the body\'s cells and fluids.It is used for intravenous infusion, rinsing contact lenses, and nasal irrigation. Saline solutions are available in various formulations for different purposes.
