A formic acid buffer solution contains 0.22 M HCOOH and 0.24 M HCOO. The pKa of formic acid is 3.75. What is the pH of the buffer? Answer:
Calculate the pH of a solution prepared by dissolving 0.370 mol of formic acid HCOOH and 0.230 mol of sodium formate HCOONa in water sufficient to yield 1.00 L of solution. The Ka of formic acid is 1.77x10. -4 Seleccione una: a. 10.463 b. 2.307 O O c. 2.099 d. 3.546 e. 3.952
A formic acid buffer containing 0.50 M HCOOH and 0.50 M HCOONa has a pH of 3.77. What will the pH be after 0.010 mol of NaOH has been added to 100.0 mL of the buffer? (Assume the addition cause negligible volume change.)
A formic acid buffer containing 0.50 M HCOOH and 0.50 M HCOONa hasa pH of 3.77. What will the pH be after 0.010 mol of NaOH has beenadded to 100.0 mL of the buffer? correct answer: 3.95 please show me step by step how to solve this problem, i couldn'tget the right answer above. Thanks in advance!
Calculate the pH of a buffer solution that is 0.30 M formic acid (HCO2H) and 0.50 M sodium formate (HCO2Na). Ka of HCO2H is 1.8 x 10-4
a 100 ml solution of 0.250 M formic acid (HCOOH) was titrated to its equivalence point with 50 mL of sodium hydroxide. The complete molecular equation for the reaction is shown below HCOOH (aq) + NaOH (aq)---------> HCOONa (aq) +H20 (l) Ka of HCOOH= 1.7 x 10 ^-4 calculate the pH at the equivalence point
You and your lab partner must prepare a 1.0 L buffer of formic acid at pH 3.5. Your lab partner started the process and has already massed out 0.23 g of formic acid (MM 46 g/mol). How many moles of sodium formate do you need to complete this buffer. The pKa of formic acid is 3.75.
