Science Vocab. 8
Term | Definition |
---|---|
Acid | any substance that produces hydrogen ions H+ in a water solution |
Base | any substance that forms hydroxide ions OH- in a water solution |
Buffer | solution containing ions that react with added acids or bases and minimize their effects on pH |
Hydronium Ion | H3O+ ions which form when an acid dissolves in water and H+ ions interact with water |
Indicator | organic compound that changes color in acids and bases |
Neutralization | chemical reaction that occurs when H3O+ ions from an acid react with OH- ions from a base to produce water molecules |
pH | a measure of the concentration of hydronium ions in a solution using a scale ranging from 0 to 14 with 0 being the most acidic and 14 being the most basic |
Salt | compound formed when negative ions from an acid combine with ions from a base |
Soap | organic salts with nonpolar hydrocarbon ends that interact with oils and dirt and polar ends that help them dissolve in water |
Strong Acid | any acid that dissociates almost completely in water. |
Strong Base | any base that dissociates completely in solution |
Titration | process in which a solution of concentration is used to determine the concentration of another solution |
Weak Acid | any acid that only partly dissociates in solution |
Weak Base | any base that does not completely dissociate in solution. |
