Q1: In part A you will prepare a dilution solution of 0.1M NaOH using a 500mL graduated cylinder and pump dispenser. The solution is then mixed and stored in the amber bottle found in your drawer. Be sure the cap is in good condition. Calculate the volume of 6.0M NaOH needed to make 450 mL of about 0.7 M NaOH. Do not include units in answer. Q2: After the first trial, in order to maximize the titration precision, the sample...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

7-3: Analysis of a Ferrous Chloride Sample Titrations provide a method of quantitatively measuring the concentration of an unknown solution. This is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) In oxidation-reduction (redox) titrations, the voltage resulting from the mixture of an oxidant and reductant can be measured as the titration proceeds....
