Name Section Date Lab Partner PRE-LAB ASSIGNMENT: CONDUCTIMETRIC TITRATION AND GRAVIMETRIC DETERMINATION OF A PRECIPITATE (Show work for All Problems) 1. Define the analyte and titrant in this experiment. How can you differentiate between them? 2. The following data below was gathered during a conductimetric titration involvinga standard solution of 0.100 M sulfuric acid, H.,SO, and 20.0 mL of barium hydroxide, Ba(OUsing LoggerPro, plot these data, perform a linear regression (refer to the Data Analysis section), and answer the questions...
What I have so far for data etc.
My question I need help with though is:
This is my data and what I have so far but this is the
question I actually need help with:
-What ions are present in the titrated solution after the
beginning of the titration but before the equivalence point? How
about after the equivalence point when the conductivity is rising?
Lastly, compare your results from 2 and 4 above with the actual
molarity of...
What is the theoretical yield of H2SO4 + BaCl2 ---> BaSO4 +
2HCl
Given data:
Concentration of BaCl2 = 0.20 M
Concentration of H2SO4 = 6 M
volume of H2S04 = 5.00 mL
What is the theoretical expected yield of precipitate as
calculated using stoichiometry?
Compare actual yield and theoretical yield. Calculate percent
yield.
Data:
Trial 1: Mass of BaSO4 precipitate = 0.191 g
Trial 2: Mass of BaSO4 precipitate = 0.187 g
What is the Millimoles of BaSO4 for...
solve for Ka of acid please

Experiment 6: The Standardization of a Basic Solution and the Determination of the MM of an Acid *Note: This experiment is relatively long unless you know precisely what to do. Read the experiment before coming to class and arrive on time. After reading through the experiment answer the following question: 1. 7.0 mL of 6.0 M NaOH are diluted with water to a volume of 400 mL. You are asked to find the molarity of the resulting solution. a. First find out how many...
