BMS1011 Wk2L1 Part C flashcards

Teaching Associates

Predominantly PhD students who assist in teaching.

Scratchy Cards

Small cards that students used to answer questions during class.

Nitrogen Atomic Number

Nitrogen has an atomic number of 7, meaning it has 7 protons.

Electronegativity

A measure of an atom's ability to attract electrons in a bond.

Polar Covalent Bond

A bond formed when bonded atoms differ in electronegativity.

pKa Value

A measure that expresses the strength of an acid; lower pKa indicates a stronger acid.

VSEPR Model

A model used to predict the geometry of molecular structures based on electron pair repulsion.

Acid-Base Equilibrium

The balance between acids and bases in a solution.

Buffer

A solution that resists changes in pH when small amounts of acid or base are added.

Henderson-Hasselbalch Equation

An equation used to calculate the pH of a buffer solution based on the concentration of acid and conjugate base.

Acidosis

A condition characterized by an excess of acid in the blood.

Carbonic Anhydrase

An enzyme that helps regulate pH in blood by converting carbon dioxide and water to carbonic acid.

Hyperventilation

The condition of breathing at an abnormally rapid rate, leading to decreased CO2 in blood and increased pH.

Bicarbonate Ion

HCO3⁻, a key component in buffering systems of blood.

Conjugate Base

The species formed when an acid donates a proton.

pH Probe

A device used for measuring the acidity or alkalinity of a solution.

Lewis Structures

Diagrams that represent the bonding between atoms in a molecule.

Trigonal Planar Geometry

A molecular shape that occurs when three groups of electrons are bonded to a central atom.

Ionic Bond

A chemical bond formed through the transfer of one or more electrons from one atom to another.
