5. In Experiment 4, we used titration to determine the total acid content of samples, which we reported in terms of molarity. Reporting acidity through pH measurements is quite different, in that we can only measure the amount of the acid in its ionized form. You were tasked to investigate a clear aqueous solution of an unknown monoprotic acid. You decided to use two Chem 16.1 methods to gather data. Method 1 - TITRATION: A 10. mL aliquot of the sample was diluted with 25 mL distilled water. Two drops of phenolphthalein were added and then it was titrated 3.54 mL of 0.048 M standardized NaOH to the endpoint. Activate W
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
please answer all :<
![b)
Calculate the molarity of the acid using the titration data.
***If we assume that the titrated unknown is a strong acid, predict the
pH of the sample.
c)
Using pH strip results, calculate the [H] concentration in the
sample before the dilution.
d)
Comparing the results from the two methods, deduce if the
unknown is really a strong acid, or if it's a weak acid. Defend in one
sentence.
e)
Rationalize the two pH readings in the pH strip test before and after
dilution. Is this to be expected?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9c8141d8-f298-42ca-ac73-dc4b587de744%2F63b26791-ca63-40c8-b156-8f7c6df8d19b%2Fke4obdb_processed.png&w=3840&q=75)
