The concentration of a solution is a measure of how much stuff is dissolved in a liquid. Activity is an effective concentration , based on something callef chemical potential.

Concentration is a basic term which relates the quantity of components dissolved in a mixture w.r.t volume , so we can have mass concentration , mole concentration w.r.t what quantity we choose to define. But more importantly this is usually done for ideal solutions and in equilibrium conditions. HoRead more

However if we look a real solution and non equilibrium conditions, we describe it by Activity which simply means what is the effective concentration of that component in the mixture. Activity is a more general term. Its basic definition is activity=(fugacity in a state/ fugacity in std state) for a component;
In case of solutions the fugacity is concentration ; in gases it’s pressure.
Simply , real conditions activity is used and ideally we can use simply concentration.
