How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to reach the equivalence point in a titration with 50.0 mL of 0.2 mol/L HCL? (A: 0.25M) The point in a titration where the moles of acid are...
Find the molarity of a solution that is made by dissolving 76.54g NaCl in enough water to make a 3,567 mL solution. Calculate the pH of a buffer solution prepared from 0.155 mol of phosphoric acid, 0.250 mol of KH_2PO_4, and enoug...
0.4(6 + x) Notice we have two expressions involving x for the amount of acid in the final solution. Therefore, these two expression must be equal to eachother, so we can set them equal and solve the resulting equation for x to find the number of milliliters...
Ascorbic acid (vitamin C, C_6H_8O_6 ) is a diprotic acid ( Ka_1= 8.00X10^{-5} and Ka_2= 1.60X10^{-12} ). What is the pH of a 0.240 M solution of ascorbic acid? Explain the different ions of aspartic acid and glycine ...
How many mL of 0.2 M H2SO4 are needed to neutralize 40 mL of 0.10 M NaOH? Note that the acid is diprotic. Defining Acid-Base Reactions: Let's consider an acid HA and a base BOH. The reaction between HA and BOH will produce BA and water as...
