Consider the solubilities of a particular solute at two different temperatures. Temperature (°C) Solubility (g/100 g H₂O) 20.0 44.4 30.0 78.2 Suppose a saturated solution of this solute was made using 81.0 g H₂O at 20.0 °C. How much more solute can be added if the temperature is increased to 30.0 °C? mass: g

a. Solid sodium hydroxide is slowly added to 125 mL of a 0.275 M iron(II) sulfate solution until the concentration of hydroxide ion is 0.0204 M. The mass of iron(II) ion remaining in solution is  ?grams. b.  Solid silver nitrate is slowly added to 150 mL of a 0.196 M sodium carbonate solution until the concentration of silver ion is 0.0673 M. The percent of carbonate ion remaining in solution is  ?%. c. Solid sodium carbonate is slowly added to 75.0 mL of a 0.435 M magnesium acetate solution until the concentration of carbonate ion is 0.0465 M. The percent of magnesium ion remaining in solution is  ?%.
