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

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9
