A colorimeter can be used for that purpose.

Solvent
It swells because of the amount of water it has inside
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants

The concentration of a solution is a measure of the amount of solute dissolved in an amount of solution. It can be expressed in many ways, with the most common way being mols solute/L of solution. Molality is another way to measure concentration; molality is mols solute/kg solvent.
The answer is...The Internet

You can directly sample gas and analyze it using various chemical tests. You can use an instrument called a correlation spectrometer or COSPEC to measure the gas emissions from a distance. These measurements are usually done from an airplane.
To measure concentration, you compare the amount of the solute to the total amount of the solution.
