concentration
describes a solution taht contains a large amount of solute per given amount of solvent
mixtures
combination of substances taht can be separated by physical processes
solution
another name for a homogeneous mixture
concentration
tells you how much solute is present compared t the amount of solvent
indicators
compounds that react with acidic or basic solutions to produce certain colors
dilute
contains a relatively small amount of solute per given amount of solvent
disollution
process of forming a solution
"Like dissolves like"
polar molecules dissolve polar molecules and nonpolar molecules dissolve nonpolar molecules

solubility
measure of how much solute can be dissolved in a certain amount of solvent
saturated
being the most concentrated solution possible at a given temperature
acid
substance that release positively charged hydrogen ions, H+, in water
hydronium ions
positively charged and have the formula H3O+
base

pH
measure of how acidic or basic a solution is, ranging from 0 to 14
indicators
compounds that react with acidic and basic solutions and produce certain colors, depending on the solutions pH
neutralization
reaction in which an acid reacts with a base and forms water and a salt
alloy

red
the color litmus paper turns when its in a acid
antacid
can help to neutralize excess acid in the stomach
