Calculate the amount of tris aminomethane
Question: Calculate the amount of Tris (hydroxlmethyl) aminomethane (Tris) necessary to make 100mL of a 0.100M Tris buffer that is equimolar in Tris-base(MW=121.1 g/mol) and Tris-HCl(MW=157.6g/mol).

Demonstrate your systemic approach to find the pH of a solution where 1.0 x 10-8 mole of sodium acetate is dissolved in 1.0 L of water. (pKa of sodium acetate = 4.76)
If 26mL of 5.2M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid? 2NaHCO3+H2SO4=Na2SO4+2H2O+2CO2
A sulfuric acid solution containing 571.6 g of H2SO4 per liter of solution has a density of 1.329 g>cm3. Calculate (a) the mass percentage, (b) the mole fraction, (c) the molality, (d) the molarity of H2SO4 in this solution.
Why could you have predicted that the pH would rise after addition of sodium acetate to pure 0.40 M acetic acid from part (a) by applying Le Chatelier's principle
