pH problem
when microorganisms reproduce they release waste products that may change the pH and prevent further reproduction. Therefore culture mediums for growing microorganisms are usually buffered. The median for the culture of lactobacilli includes a buffer prepared by dissolving 25 grams K2HPO4 and 25 grams KH2PO4 in water and diluting to 250.0 mL. The question is what is the pH of the buffer solution? and before the culture medium is used it is diluted to 1.000 L with distilled water. So then what would be the pH after dilution as well?
What is this?

- Specific Rotation - A sample of 150 mg of an rganic compound is dissolved in 7.5 mL of water. The solution is placed in a 20-cm polarimeter tube and the rotation measured in a polarimeter. The rotation observed was +2.676 degrees. Distilled water in the same tube gave a reading of +0.016 degrees.
