Use this formula to calculate ionic strength: I= 1/2 n∑i (CiZi )squared, where "I" represents ionic strength, "n" represents the number of ions in solution, "i" represents the specific ion in solution, "Ci" represents the concentration to the /th species, such as moles per liter, ...
So that means, 1 mole of Fe2+ in FeSO4 require 4 x 10-4 mol of potassium manganate to be oxidised to 1 mole of Fe3+. Since the ionic equation shows 5 moles, than we multiply by 5...and we get the number of moles of Fe2+ in 10cm3 of solution. Then we x by 10 to get th...

Equilibrium Constant Definition Theequilibrium constantis the value of the reaction quotient that is calculated from the expression forchemical equilibrium. It depends on the ionic strength and temperature and is independent of the concentrations of reactants and products in a solution. Calculating the ...
Calculate the force of attraction according to F = k * q1* q2/ d2. Using the previously obtained values for calcium bromide and using 8.99 x 109as the value for k gives F = (8.99 x 109) * (3.8 x 10-19) * (1.9 x 10-19) / (3.96 x 10-10)2. Under the rules of the scient...
Calculate the enthalpy of the reaction: CO(g) + 2 H2(g) ⟶ CH3OH(g) The enthalpy of the bonds in the molecule can be determined from the enthalpies of the individual bonds. For this, refer to a table such as the page given in the Resources. ...
I is the ionic strength in mol/L, γ is the activity coefficient. Steps: Use the given values for I (ionic strength) and γ (activity coefficient). Plug them into the formula to calculate α (ion size). Example: For I = 0.01 mol/L and γ = 0.85, the ion size α will be approx...
