Solubility Rules Memorization ?
When we solve problems are the little chemistry symbols at the bottom of each reactant/product (like (aq),(l), or (s)) already given? Or do we need to memorize the solubility rules in order to determine whether the reactant/product is aqueous or not? (Just for labelling)? i.e Will the word problems explicitly state it's a solid? I don't know if this'll be important but I was just wondering if I need it.

Re: Solubility Rules Memorization ?
So far, in lecture, discussion and in homework, the state of matter has been given for the molecular compounds we have had to balance in chemical equations, either directly or through context clues in the problem itself. That being said, I would say use these context clues (say, if the problem said sodium chloride is in solution, you would know it is in an aqueous state) to guide yourself on what to label for the state of matter. I would definitely double check with your TA this week or in lecture this Friday to make sure though.

For a couple of the examples given in my discussion last week where we were practicing writing out and balancing chemical equations, we weren't given states of matter, but for those questions, it was easier to use context clues to figure it out. It might be a little harder to figure out which reactants/products are aqueous, though.

Re: Solubility Rules Memorization ?
To build off of that question, if the question shows the solubility like (l) or (s) or (aq) would it matter if throughout our problem solving and the final answer it does not have the solubility or do we have to include it throughout and the final answer?
