ChemicalReactions
Term | Definition |
---|---|
Chemical Reactions | occur when chemical bonds form or break between atoms, ions or molecules |
Reactants | are the starting materials of a chemical reaction: the atoms, ions or molecules |
Products | are substances formed at the end of the chemical reaction |
Synthesis Reaction | more complex chemical structure is formed |
Decomposition Reaction | chemical bonds are broken to form a simpler chemical structure |
Exchange Reaction | chemical bonds are broken and new bonds are formed |
Electrolytes | substances that release ions in water |
Acids | electrolytes that dissociate to release hydrogen ions in water |
Bases | substances that release ions that can combine with hydrogen ions |
pH Scale | indicates the concentration of hydrogen ions in a solution |
Neutral | a pH of 7 indicates a greater concentration |
Basic | a pH > 7 indicates a higher concentration |
Acidosis | occurs when blood pH drops to 7.0 through 7.3 |
Alkalosis | occurs when blood pH rises to 7.5-7.8 |
