S Figure 1 pH = 10.35 Mg (OH)₂ (s) Mg2+ (aq) + 2 OH (aq) (A) Distilled water (B) NaNO3 (aq) (C) HCl (aq) (D) KOH (aq) Figure 2 A student prepared a saturated aqueous solution of Mg (OH)₂ and measured its pH, as shown in figure 1 above. Then the student added a few drops of an unknown solution to the test tube and observed cloudiness in the solutions as shown in figure 2. On the basis of ...
The solubility of sodium chlorate (NaClO3) at 20 oC is 959 g per 1.000 kg of water. If a saturated solution is made using 884.1 g of water, how much more water (in g) needs to be added for the solution to have a boiling point of 105.0 oC? The Kb is 0.512 oC/m and the density of water is 1 g/mL. (Enter in standard notation with zero digits after the decimal) The solubility of sodium chlorate ...
