What does the formula for an acid start with? What is an Acid A solution in which hydronium ions are present when mixed with water What does the formula for an acid start with? Starts with an “H” Characteristics of an ACID Sour, Reacts with metals, electrolyte, burns the skins What is a Base A solution in which hydroxide ions are present

What does the formula of a base end with? Characteristics of a Base Ends in “OH” Characteristics of a Base Bitter, soaps, proton acceptors, slippery, burn skin pH range from 0-6 Acid pH range from 0-2 Strong Acid

pH range from 8-14 Base pH range from 10-14 Strong Base pH of 7 Neutral Pure Water Neutralization A process where an acid and base are chemically combined to form a salt and water

Red Litmus Paper What are the products of a Neutralization Reaction A salt and water What type of reaction is a Neutralization Reaction Double Replacement Reaction Blue Litmus Paper Acid—Turns red Base—No Change Red Litmus Paper Acid—No Change Base—Turns Blue

pH Paper Phenolphalein Solution Solubility Acid—red, orange, and yellow tints Base—blue-green to dark blue tints Phenolphalein Acid—Clear Base—Hot Pink Solution Where one substance must dissolve in another Solubility Ability of a solute to dissolve in a solvent

Solute Solvent Speed up Dissolving Electrolytes Part being dissolved in the solvent Solvent Part that does the dissolving Speed up Dissolving Stirring Heating Powdering Electrolytes Solution heat conducts electricity Ex: salt and water

Nonelectrolytes Unsaturated Saturated Supersaturated Solution that doesn’t conduct electricity Ex: Sugar and water Unsaturated Holding little solute in much solvent Saturated Holding as much solute at a given temperature Supersaturated More solute in the solvent at a high temperature

Acid, Base and Solutions Unit Dissociation The separation of ions in an ionic compound as the compound dissolved Ionization The process by which neutral molecules gain or lose electrons Dispersion Breaks into smaller pieces that spread throughout the water Acid, Base and Solutions Unit
