-NEUTRALIZATION REACTIONS

Can you help me with this one? The given problem is in the image that I've attached

1.  Based on the given problem, What is the molecular weight of potassium biphthalate (C8H5KO4)?

2.Based from the given problem, what is the mEq of potassium biphthalate?

3.Based from the given problem, what is the Normality of the sodium hydroxide solution?

Would you please provide a separate solution to each question, thankyou!

 

 

Here are the instructions on how will you write the answers:

1. All answers to be entered via short answer are in the NUMERICAL FORMAT and presented up to the 3rd decimal place. ADD TRAILING ZEROS if necessary, to complete your answer. NO NEED TO INCLUDE THE UNIT for now.

For uniformity of answers, please be guided by the following examples:
- If your answer is 5.627594, enter 5.628
- If your answer is 3.129934, enter 3.130
- If your answer is 8.38, enter 8.380
- If your answer is 1.2, enter 1.200
- If your answer is 25, enter 25.000
- If your answer is less than the value of 1, always place a zero before the decimal point (E.g.: if 0.5, enter 0.500)

2. In cases for answers in the EXPONENTIAL FORMAT, please be guided by the following examples and format:
- Do not convert your answer to decimal format
- If your answer from the calculator is 1.23454566 x 10E-4, enter 1.235x10^-4 (no spaces in between)
- If your answer from the calculator is 7.379566 x 10E-5, enter 7.38x10^-5 (no spaces in between)

3. The ATOMIC MASSES should be rounded to the NEAREST WHOLE NUMBER. (E.g. Hydrogen: 1.00784 = 1.000)

Based from the given problem, What is the molecular weight of potassium
biphthalate (C8H5KO4)? *
Part 1: Alkalimetry
Preparation and Standardization of IN Sodium Hydroxide
A. Preparation
Dissolve 14.7 grams of sodium hydroxide pellets in 100 ml of carbon-dioxide free water.
Cool the solution to room temperature
Add a freshly prepared saturated solution of barium hydroxide until no more precipitate forms.
Shake and filter.
Transfer it in a 250 ml volumetric flask, then add sufficient quantity of carbon dioxide free water to
make 250 ml.
B. Standardization
Weigh accurately about 5 grams of potassium biphthalate, previously crushed lightly and dried at
120 degrees Celsius for 2 hours and dissolve it in 75 ml of carbon dioxide free water.
Add 2 drops of phenolphthalein TS.
Transfer 50 ml of the sodium hydroxide solution in a Buret and titrate the potassium biphthalate
solution with the sodium hydroxide solution until it produces a permanent pink color.
Note: 24 ml NaOH solution was used to change the color from colorless to pink color
*Titer Value: Each ml of 1 NNaOH is equivalent to 204 mg of Potassium biphthalate
