QuestionAnswer
What is potable water? Water that is fit for human consumption.
What is an aquifer? An aquifer is a great pool of water trapped in sand and gravel 50-500 feet below the surface.
What is surface water? Surface water is water from lakes, rivers, and reservoirs.
What is groundwater? Groundwater is water pumped from wells that have been drilled into underground aquifers.
What is a solute? Solutes are those substances that dissolve in a solvent.
What is a solution? A solution is a homogeneous mixture of uniform composition.
What is a solvent? A solvent is a substance capable of dissolving other substances.
What is an aqueous solution? Aqueous solutions are solutions in which water is the solvent.
What is a mineral? A mineral is a naturally occurring element or compound that usually has a definite chemical composition, a crystalline structure, and is formed as a result of geological processes.
What is concentration? Concentration is the ratio of amount of solute to amount of solution.
What is percent? Percent is parts per hundred.
What is parts per million (ppm)? Parts per million is 1 part per million.
What is a liter(L)? A liter is the volume occupied by 1000g of water at 4 degrees Celsius.
What is meant by parts per billion (ppb)? Parts per billion is 1 part per billion.
What is molarity(M)? Molarity is defined as the number of moles of solute present in one liter of solution. Molarity(M)= {(moles of solute)/(liter of solution)}
What is a volumetric flask? A volumetric flask is a type of glassware that contains a precise amount of solution when filled to the mark on its neck.
What is meant by the term electronegativity? Electronegativity(EN) is a measure of an atom's attraction for the electrons it shares in a covalent bond.
What is a polar covalent bond? A polar covalent bond is a covalent bond in which the electrons are not equally shared, but rather displaced toward the more electronegative atom.
What is an intramolecular force? An intramolecular force is a force that exists within a molecule.
What is an intermolecular force? An intermolecular force is one that occurs between molecules.
What is a hydrogen bond? A hydrogen bond is an electrostatic attraction between a hydrogen atom bearing a partial positive charge in one molecule and an O, N, or F atom bearing a partial negative charge in a neighboring molecule.
What is density? Density is the ratio of mass per unit volume.
What is specific heat? Specific heat is the quantity of heat energy that must be absorbed to increase the temperature of 1 g of a substance by 1 degree Celsius.
What is a conductivity meter? A conductivity meter is an apparatus that produces a signal to indicate that electricity is being conducted.
What's a nonelectrolyte? A nonelectrolyte is a nonconducting solute when in aqueous solutions.
What's an electrolyte? An electrolyte is a conducting solute in an aqueous solution.
What's an ion? An ion is an atom or group of atoms that has acquired a net electric charge as a result of gaining or losing one or more electrons.
What's a cation? A cation is a positively charged ion.
What's an anion? An anion is a negatively charged ion.

A ______ is a graph that is made by carefully measuring the absorbancies of several solutions of known concentration for the species being analyzed. Calibration graph
_______ is a broad general term describing any process that removes ions from salty water. Desalination
_______ is a separation process in which a solution is heated to the boiling point and the vapors are condensed and collected. Distillation
______ is the natural tendency for a solvent to move through a membrane from a region of higher solvent concentration to a region of lower solvent concentration. Osmosis
______ is using pressure to force the movement of a solvent through a semipermeable membrane from a region of high solute concentration to a region of lower solute concentration. Reverse osmosis
