Coke has a pH of 2.6. Assuming that the acidity of the Coke is due solely to carbonic acid and the density of Coke is 1.11g/mL, then the carbonic acid concentration calculates to be 0.86% by mass in Coke. What is the volume of 0.02M sodium hydroxide required to neutralize an entire can of Coke which is 374g? The molar mass is carbonic acid is 62g/m.

3. To make a buffer solution, you can start with a solution of a known number of moles of the base form (A) and add a strong acid until you have neutralized the correct number of moles of the base to have the correct A HA ratio for the buffer you require. For the example using HF in the background information: a. How many moles of the base form (A) are required to start? HINT: The acid form (HA) will...

2. Mass versus Light One of the primary goals of every galaxy survey is to measure the distribution of the luminosities of galaxies, which has been found to be well parameterized by the luminosity function L/L- where φ(L)dL is the number density of galaxies with luminosity between L and L + dL, and φ*, L*, and a are parameters to be determined from galaxy surveys (a) Show that the luminosity density of galaxies, J, is related to ф*, L*, and...

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...
