Solubility Product Solubility is defined as the number of grams or moles of compound needed to saturate 100 g of water, or it can also be defined in terms of 1 kg of water, at a given temperature F...
Calculating pH of Buffer Solutions The pH of a buffer solution can be calculated using: The Ka of the weak acid The equilibrium concentration of the weak acid and its conjugate base (salt) To deter...
Buffers A buffer solution is a solution in which the pH does not change a lot when small amounts of acids or alkalis are added A buffer solution is used to keep the pH almost constant A buffer can ...
Calculating [H+] & pH If the concentration of H+ of an acid or alkali is known, the pH can be calculated using the equation: pH = -log [H+] Similarly, the concentration of H+ of a solution can ...
Calculating pH, Ka, pKA & Kw pH The pH indicates the acidity or basicity of an acid or alkali The pH scale goes from 0 to 14 Acids have pH between 0-7 Pure water is neutral and has a pH of 7 Ba...
Conjugate Acids & Bases A Brønsted acid is a species that can donate a proton For example, hydrogen chloride (HCl) is a Brønsted acid as it can lose a proton to form a hydrogen (H+) and chlorid...
Calculating Free Energy Change Using Standard Electrode Potentials The standard free energy change can be calculated using the standard cell potential of an electrochemical cell ΔGꝋ = - n x Ecellꝋ ...
The Nernst Equation Under non-standard conditions, the cell potential of the half-cells is shown by the symbol Ecell The effect of changes in temperature and ion concentration on the Ecell can be d...
