BUFFER SOLUTION (ACID) An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. Objectives: 1. Measure the pH of the unknown solution first with indicators and then with pH paper. 2. compare the buffer solution with both a strong acid and a weak acid materials: 2 30 mL beakers 2 100mL volumetric flask 1 10mL pipet 2 aspirator 1 50mL graduated cylinder 1 10mL graduated

Solution to Tutorial 4 Given: F = 1000 kg-mole/hr‚ xF = 0.20 (ethanol is MVC) Feed is saturated liquid‚ thus q = 1.0 xD = 0.80‚ xB = 0.02 (maximum); R = 5/3 First‚ plot the equilibrium curve using the VLE data given. Note that you need to convert mole% ethanol into mole fraction. Then‚ apply the McCabe-Thiele method to find the number of theoretical (equilibrium) trays required for the separation. Step 1: Since R and xD are known (5/3‚ and 0.80 respectively)‚ plot the ROL equation - it
