<u>Answer:</u> The p-function of and
ions are 2.51 and 2.14 respectively.
<u>Explanation:</u>
p-function is defined as the negative logarithm of any concentration.
We are given:
Millimolar concentration of zinc nitrate = 3.1 mM
Millimolar concentration of calcium nitrate = 4.2 mM
Converting this into molar concentration, we use the conversion factor:
1 M = 1000 mM
- Concentration of zinc nitrate = 0.0031 M = 0.0031 mol/L
1 mole of zinc nitrate produces 1 mole of zinc ions and 2 moles of nitrate ions
Concentration of zinc ions = 0.0031 M
Concentration of nitrate ions in zinc nitrate,
- Concentration of calcium nitrate = 0.0042 M = 0.0042 mol/L
1 mole of calcium nitrate produces 1 mole of calcium ions and 2 moles of nitrate ions
Concentration of calcium ions = 0.0042 M
Concentration of nitrate ions in calcium nitrate,
To calculate the concentration of nitrate ions in the solution, we use the equation:
Putting values in above equation, we get:
Calculating the p-function of zinc ions and nitrate ions in the solution:
- <u>For zinc ions:</u>
- <u>For nitrate ions:</u>
Hence, the p-function of and
ions are 2.51 and 2.14 respectively.
