Please help with #10-12. I'm not sure how to calculate the new theoretical pH when increasing buffer pH with NaOH. Thank you 1. pH of the buffer needed to prepare:... 10. 0 (1).... Na z CO, NaH COs 2. Reagents selected to make a buffer: (2).... 3. Reasons for selecting the reagents:I chose these reagents because our assigned pH is 10, and the pKa of Sodium Carbonate is close to 10, along with the matching acid Sodium Bicarbonate 4. Calculated amount of reagents needed to prepare a buffer: reagent 2 Total Buffer volume: 100mL reagent 1 [Buffer]: 0.05 M 0.1689 g or ml 0.2862 g or ml 1.593x10°| moles 3.407x10| moles 5. pH of a buffer measured with pH-meter. 10.07 6.

A solution (containing one of the following cations: Hg22+, Cd2+, Sn2+, NH4+) was tested with various reagents and the following results were obtained: What is the cation present in the sample?" Please refer to the table attached Hg22+ Cd2+ Sn2+ NH4+
I am extremely confused as to the logic behind these conceptual/theory problems can you please add a lot of detail: Consider a buffer solution where [weak acid] > [conjugate base]. How is the pH of the solution related to the pka value of the weak acid? If [conjugate base] > [weak acid], how is pH related to pka?
Only typed solution.

Question 7 Volhard method is supported by the following statements EXCEPT Choose the best answer. Titration can be done even at a pH lower than 6.5 The endpoint of the back titration is the formation of a colored complex ion. Involves the addition of excess AgNO3 to a halide solution, followed by back titration of the excess by KSCN The acidic pH condition prevents the appearance of the green suspension at endpoint.
