Question- Calculate the pH of a buffer made by dissolving 1 mol formic acid (hcooh) and 1.0 mol Sodium formate (HCOONa) in 1.0 L of solution (pHa = 3.74)
I am not able to solve the above problem somebody help me to get the correct answer
Which of the following tests could differentiate between pentanal and 3-pentanone, also what would occur.
using an aqueous solution of 75.00 ml of hcooh is titrated with a 0.150 m sodium hydroxideaqueous solution .after

Compute the concentration of oxalate ion (C2O4) in a 0.175 M solution of oxalic acid (C2H2O4). For oxalic acid, Ka1 =6.5*10-2 and Ka2 = 6.1 * 10-5
Question- A 0.25-mole quantity of CuSO4 is added to a liter of 1.0 M NH3 solution. What is the concentration of Cu2+ at equilibrium. [The formation constant for Cu(NH3)42+ is
Which one of the following compounds is not consistent with the terminology of a complex? A) [Cu(NH3)4]2+ B) D) [Cr(NH3)6]Cl3
The solubility product constant (Ksp) for the dissolution of CdC2O4 as represented by the chemical equation is 1.5 x 10-8.
you have two flasks of equal volume. flask a contains h2at 0degc and 1 atm pressure. flask b contains co2 gasat 0degc
How would you find the Ksp of a salt using only molecular weight and solubility?
