Using the solubility of Ca(IO3)2 that you determined in 0.01M KIO3 as a solvent, calculate the value of Ksp using only concentrations, that is assuming that all activity coefficients are 1.0. You should report 3 significant figures.

Explanation:

Dissociation of Ca(IO₃)₂ is as follows:

Ca(IO₃)₂      ⇄   Ca²⁺    +     2IO₃⁻

This implies that for every mole of  Ca(IO₃)₂  that dissolves in water' 1 mole of  Ca²⁺ is obtained and 2 moles of IO₃⁻ is obtained.

The solubility in mol/L when  Ca(IO₃)₂  is added to KIO₃ =  0.00341

Concentration of Ca²⁺ will be = 0.00341 M  ˣ 1 = 0.00341 M ( i.e equal to the solubility of Ca(IO₃)₂)

Concentration of IO₃⁻ will be = 0.00341 M  ˣ 2 = 0.00682  M

IO₃⁻ is also obtained from the dissociation of KIO₃ in water. the IO₃⁻ obtained from this process is = 0.01 M

The total concentration  of IO₃⁻ now = 0.00682  M + 0.01 M = 0.01682 M

The solubility product can be calculated by the formula:

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
