'Which' is used when talking about one of a group of things known or implied by the speaker and listener. 'What' can refer to more unknown things, e.g.
1 Which is best, coke or lemonade?
2 What is lemonade?
While 'what' can be used in sentence 1 (what is best, coke or lemonade?) this use is more informal.
'Which' could only be used in sentence 2 if, for example, there were lots of cups on the table with different clear fluids inside, and the speaker wanted to know which one contains lemonade. This would have a very different meaning from 'what is lemonade?'
"Which" is used when choosing between a known set of options, while "what" is used when asking about something unknown or unspecified. For example, "Which of these two books do you prefer?" versus "What is your favorite book?"
