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

carrying value of an asset is not recoverable. Per the same standards‚ carrying value is not recoverable “if it exceeds the expected future cash flows to be derived from the asset on an undiscounted basis” (FASB‚ ASC 360-10). In the Property Solutions Inc. case‚ the carrying value of the building on 10/1/2017 was $1‚650‚000 and the expected future cash flows are $1‚214‚940. Per the definition of impairment loss stated above‚ the asset is impaired. In calculating the loss‚ we must compare the carrying
