If ammonia was added to a saturated solution of copper(II) iodate in a equilibrium with its precipitate, would the copper ion concentration increase, decrease, or stay the same? Why?
How many g or H2O are created with excess CO2 and 168 g of KOH from the following chemical reaction? CO2 + 2 KOH -----> K2CO3 + H2O
Eventually, the amounts of the three species do not change further; the system has reached equilibrium. (at this point, approximately 22% of the HI has decomposed.) Describe what is happening in this system at the molecular level.
