You are on a field trip to a nearby lake for biology class and want to perform a quick analysis of the water’s approximate ph level. which ph measurement system would you use and why?

Sample Response: Using pH paper would be best for doing a quick measurement in the field. It does not need to be calibrated and the papers provide an instant estimate. Answer on Ed

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).
