Question

How many cm3 of 1% solution of sodium formate should be added to 100cm3 of HCl solution with C=0.05M to obtain a solution with pH=3.7

Answer 1

Step-by-step explanation:

The exact answer to this question depends on the pH of the HCl solution and the buffer capacity of sodium formate, which can vary depending on various factors such as temperature and impurities. To determine the volume of sodium formate needed to obtain a pH of 3.7, it would be necessary to perform a titration experiment and measure the pH of the solution at various points to determine the buffer capacity of the sodium formate.
