Phenol red is a ph indicator routinely used to monitor the ph of solutions in laboratories. it is reddish-orange in neutral solutions, yellow in acidic solutions, and magenta in basic solutions. what color would a neutral, phenol-red containing solution turn if you started blowing your exhaled air into it using a straw?

The answer is yellow .

That is if you started blowing your exhaled air into a phenol-red containing solution, then it color will change to yellow.

It changes it color as we blow exhaled air into it as we are introducing carbon dioxide into the mixture.

And as carbon dioxide concentration increases, the H ion concentration increases that means the solution becomes acidic that is it becomes yellow.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
