What is the solution to lemonade

If you mean what is in the solution, then that would be water, sugar, and lemonade powder (That is, if it is not homemade). If this is homemade lemonade, then is is water, sugar, lemon juice, and if you've ever seen homemade lemonade, there's also little bits of lemon floating around too, in which case this would technically be a suspension rather than a solution.

Lemons first then sugar then water then water and mix i do it like that first but people do it another way
