AP Biology Topic 1.1

molecule that donates hydrogen ions and increases the concentration of hydrogen ions in a solution

• acid
• evaporation
• hydrophilic
• adhesion

attraction between water molecules and other molecules

• adhesion
• buffer
• hydrogen bond
• specific heat capacity

molecule that donates hydroxide ions or otherwise binds excess hydrogen ions and decreases the concentration of hydrogen ions in a solution

• base
• acid
• litmus paper (pH paper)
• specific heat capacity

substance that resists a change in pH by absorbing or releasing hydrogen or hydroxide ions

• buffer
• sphere of hydration
• base
• surface tension

occurs because water molecules are attracted to charges on the inner surfaces of narrow tubular structures such as glass tubes, drawing the water molecules to the sides of the tubes

• capillary action
• evaporation
• buffer
• cohesion

NGSS.HS-ESS2-5

intermolecular forces between water molecules caused by the polar nature of water; responsible for surface tension

• cohesion
• specific heat capacity
• heat of vaporization of water
• acid

Tags

NGSS.HS-PS1-3

release of an ion from a molecule such that the original molecule now consists of an ion and the charged remains of the original, such as when water dissociates into H+ and OH-

• dissociation
• base
• electronegativity
• buffer

NGSS.HS-PS1-2

ion necessary for nerve impulse conduction, muscle contractions and water balance

• electrolyte
• electronegativity
• sphere of hydration
• litmus paper (pH paper)

Tags

NGSS.HS-LS1-3

ability of some elements to attract electrons (often of hydrogen atoms), acquiring partial negative charges in molecules and creating partial positive charges on the hydrogen atoms

• electronegativity
• specific heat capacity
• evaporation
• acid

NGSS.HS-PS1-1

separation of individual molecules from the surface of a body of water, leaves of a plant, or the skin of an organism

• evaporation
• electronegativity
• buffer
• cohesion
