How do I identify relative concentrations of solutions vs cells in an experiment?
AlexiaRgp0028
If you place the cells in the unknown solution and it shrinks/shrivels up, then the unknown solution is hypertonic. That means it has higher concentrations of permeable ions than does the cell. If the cell ruptures/bursts, then the opposite is true. In that case, the unknown solution has a lower concentration of ions (hypotonic). If nothing happens to the cell and it maintains the original morphology, then the unknown solution is isotonic and has approximately the same ionic concentration as inside the cell. These observations are based on the principle of osmosis.

When a reaction is at equilibrium is the equilibrium constant is equal to 1?
need not be..equilibrium constant is just a ratio of relative concentrations of products (multiplication of concentration in case of more than one products) to the concentration of reactants (multiplication of concentrations of reactants in case of more than one reactants)..the equilibrium concentration can be a very small number or can be a very number as well depending upon the relative concentrations of reactants and products..Unity equilibrium constants is just a special case which shows that the concentrations of products and reactants are equal..
What does substance's pH tell you?
Ph tells you how acidic/basic a solution is. It is a measure of the relative concentrations of H+ ions to OH- ions.
