1. A buffer is prepared by adding 1 5 . 0 0g sodium acetate ( MM= 82.0343 g / mol ) and 12.50 g

In the first part of the question we have the buffer, ammonium bromide ammonia. So here ammonium

pH is equal to pKa plus the log of A negative divided by the HA. Alright, when we put in the val

We have a buffer that was prepared by adding 4 .95 gram sodium acetate to 250 milliliters of .15

Hello students, hope you are doing great. In this question we are asked to find out the pH of a

Question

1. A buffer is prepared by adding \( \mathbf{1 5 . 0 0} \mathrm{g} \) sodium acetate ( \( \mathrm{MM}= \) \( 82.0343 \mathrm{~g} / \mathrm{mol} \) ) and 12.50 g acetic acid (MM= \( \mathbf{6 0 . 0 5 2} \mathrm{g} / \mathrm{mol}) \) to enough water to make 500 mL of solution. a. What is the \( \mathbf{p H} \) of the buffer? b. The buffer is diluted by adding enough water to make 1.50 L of solution. What is the pH of the diluted buffer? 2. A buffer is prepared by adding 5.50 g ammonium chloride (MM \( =53.491 \mathrm{~g} / \mathrm{mol} \) ) and 0.0188 mol of ammonia to enough water to make 155 mL solution. a. What is the \( \mathbf{p H} \) of this buffer? b. If enough water is added to double the volume, what is the pH of the solution? 3. A solution with a \( \mathbf{p H} \) of 8.73 is prepared by adding water to 0.614 mol of NaX to make a 2.50 L solution. What is the pH of the solution after 0.219 mol of HX is added? 4. An aqueous solution of 0.057 M weak acid, HX has a pH of 4.65. what is the pH of the solution if 0.018 mol KX is dissolved
