I'm having trouble understanding the concept of activity. What exactly is it?

Activity is a way of describing the effective concentration under non-ideal conditions. Non-ideal conditions lead to differences between observed and calculated values, hence it is necessary to assign activities to balance these differences. Here is a good link on the topic:
