Investigation - Solution Colour and Ion Concentration Aim: To investigate whether solution colour can be used to reliably determine the concentration of coloured ions in a solution. Hypothesis: the concentration of permanganate ions in the solution is inversely proportional to the percentage transmission of light through the solution. Dependent variable: concentration of permanganate ions. Independent variable: percentage transmission of light through the solution. Equipment: 20 ml

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)
