Chapter 2, Problem 25P
Summary Introduction

To determine: The weight in grams of sodium dihydrogen phosphate (NaH2PO4∙H2O; FW 138) and disodium hydrogen phosphate (Na2HPO4; FW 142) needed to prepare 1L of a standard buffer at pH 7.00 with a total phosphate concentration of 0.100 M.

Introduction:

The pH of the internal fluid of the cells is maintained by the phosphate buffer system. The buffer comprises of dihydrogen phosphate ions and hydrogen phosphate ions. The addition of extra hydrogen ion in the fluid of the cellular region, results in change in pH which is then neutralized by the hydrogen phosphate ion. Similarly, the change in pH caused by the action of the hydroxide ions is neutralized by the dihydrogen phosphate ion.

The right-hand side of this reaction shows the product of an aldol condensation. What are the reactants missing from the left-hand side? Draw them below. ? NaOH Δ If there aren't any reactants that would lead to these products under the reaction conditions given, just check the box under the drawing area. Note for advanced students: don't worry if the reactants you propose might also make some other products under these reaction conditions. Just make sure the product above is one of the major products.
Please help! I need to identify four labeled unknown bottles based off of their colors doing titration using phenlphtalein. I've included my answers, but I wanted to make sure they were correct and if not, what will be correct thank you in advance.
An organic chemistry Teaching Assistant (TA) suggested in your last discussion section that there is only one major organic product of the following reaction and that this reaction builds a ring. If the TA is right, draw the product in the drawing area below. If the TA is wrong, just check the box below the drawing area. NaOH ?
