(meaning all reactants and products are aqueous), then put a big X over the box KBr (aq) (K +1 , Br -1 ) Na 2 CO 3 (aq) (Na +1 , CO 3 -2 ) CaS (aq) (Ca +2 , S -2 ) NH 4 OH (aq) (NH4 +1 , OH -1 ) AgNO 3 (aq) (Ag +1 , NO 3 -1 ) BaCl 2 (aq) (Ba +2 , Cl -1 ) Al(NO 3 ) 3 (aq) (Al +3 , NO 3 -1 ) *H 2 SO 4 (aq) (H +1 , SO 4 -2 ) The ions remain dissociated in water, meaning un-bonded The ions will usually form a strong ionic bond with another ion , resulting in a precipitate (solid), gas, or liquid

H Chem Unit 5 Using solubility rules & net ionic equations Name: _______________________________________ p. 3 *???H +1 isn’t on the solubility rules! Let’s go with this for now: assume when H+ is in water it only bonds with OH- to make the liquid water. Otherwise, the H+ remains a “dissociated” ion. And you don’t have to memorize b/c I wrote it right here for you Molecular Equations : These are what you are expected to write unless told to write the net ionic. Every species is included in the molecular equation, including spectators, and ionic compounds are written intact. Molecular equations may or may not include phase symbols. Net Ionic Equations : These equations show only the species which underwent a change in oxidation number OR phase of matter (ex: aqueous solid or gas or liquid (molecule, such as water) or vice versa) and all aqueous ionic compounds and acids are written as separate ions (remember to include the oxidation number if it isn’t 0…meaning every ion will need a charge). Ionic compounds that are in any phase other than aqueous (usually solid) are written intact. Molecular substances, with the exception of acids, are also written intact regardless of phase of matter. Phase symbols are recommended. The ions which do not undergo a change are called ‘ spectator ions ’. Again, be careful to include the charge/oxidation number for any ion that is NOT part of a compound. You will need to use the solubility rules to determine if an ionic substance dissociates in water ( = split into ions and is labeled ‘aqueous’ ) or remains intact ( = does not split into ions and labeled ‘solid’). Note: If there is no change in oxidation numbers or phase of matter, then there is NO chemical reaction. Write N.R. in place of products.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
