Document Summary
Bond & molecular polarity, intermolecular forces, gas laws, solutions, chemical equations, precipitation reactions. Monday, 11 / 15 (no clicker points optional day) Monday, 11 / 15 @ 6 pm in a101. When you mix k3po4 (aq) and ca(no3)2 (aq) to form ca3(po4)2 (s) and kno3 (aq), what is the stoichiometric ratio of ca3(po4)2 (s) to kno3 (aq) in the molecular equation: 1:2, 1:6, 2:3, 2:1, 3:1. 2k3po4 (aq) + 3ca(no3)2 (aq) ca3(po4)2 (s) + 6kno3 (aq) The precipitate is the insoluble solid that falls out of solution. Ab (aq) + cd (aq) ad (s) + cb (aq) If one of the combinations is insoluble, you have a precipitation reaction. Once you know the possible products, refer below to determine if any of them are insoluble. Acid produces h+ ions when dissolved in water. Base produces oh- ions when dissolved in water.
