sorry the picture is sidaways. can someone please help with the
second question?
Q1.
find how much volume is required fo the titration
From the graph, it is about 35 mL... most likely 34.5 mL as stated by the user/student
Q2
what is the molarity of HA in the original solution
If Vacid = 50 mL
then, calculate molarity via
mol of acid = mol of base
Macid*Vacid = Mbase*Vbase
Macid*50 = 0.099*34.5
Macid = 0.099*34.5/50 M = 0.06831 M for the acid

please help with question 3 part b on the first picture?
please step by step explain thank you
he leo the acid 3. Following the Procedure of this experiment, a student monoprotic acid with 0.100M NaOH and monitored the titration with a pH meter. His titration titrated 0.653 g of an unknown weak, monoprotic acid with data were: volume of NaOH solution added, mL volume of NaOH solution added, mL pH 0.00 2.00 4.00 6.00 3.30 22.00 24.00 26.00 28.00...
Molarity for NaOH = 0.08732. In a second titration with the same solution of NaOH as used in Question #1, the student weighs out a sample of KHP of 0.359 g. Calculate the volume of the NaOH solution needed to neutralize this sample of KHP. 3. A monoprotic weak acid with the general formula of HA will react with a base, such as NaOH. Write the neutralization equation which describes the reaction. 4. If K, for the weak acid, HA is 1.8...
can someone please help me out with questions 1-5, please
To add more information this was given to me for a lab that used
a weak acid and we added a strong base through titration. We just
observed how the ph changes. Later we then used a buffer with a
weak acid to see how buffers affect ph change. These questions are
basically surrounded around those topics to help us prepare.
However, I'm kinda confused about answering them because weak...

someone help me answer these 5 questions and figire this graph out
please?
Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...

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...

Pre-Lab Questions: 1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCI stock solution. In your response to this question, be very specific about the quantities of stock solution and...
