A metal ion at the centre of a complex

A molecule or ion with a lone pair that forms a coordinate bond to a metal ion

A photon absorbed by a d orbital

An electron promoted between energy levels

The nucleus emits visible light

Ligands split the d orbitals and an electron is promoted across the gap (a d-d transition), absorbing visible light

The metal reflects all visible light equally

The complex contains a fluorescent dye

It has an empty d subshell

It has a full d10 subshell, so no d-d transition is possible

It absorbs only ultraviolet light

It has no electrons at all

It shifts the equilibrium to the right

It shifts the equilibrium to the left

It has no effect on the position; it only reaches equilibrium faster

It increases the value of K

[H+] = c

[H+] = the square root of (Ka times c)

[H+] = Ka divided by c

[H+] = Ka times c

The weak acid neutralises the added acid

The conjugate base reacts with the added hydrogen ions

Water evaporates to remove the acid

The buffer turns the acid into a gas

When delta G = 0, giving T = delta H divided by delta S

When delta H = 0

When the temperature reaches 100 degrees Celsius

When delta S = 0

fast

thermodynamically feasible, but not necessarily fast

endothermic

at equilibrium

From the coefficients in the balanced equation

By experiment, usually from initial-rate data

From the molar masses of the reactants

From the value of delta G
