We performed an experiment in lab on pH titration. We titrated a 0.1033 M NaOH solution into an unknown concentration of a weak acid (25.00 mL). It also says the unknown acid will have a concentration of about 0.1 M. I already found the Equivalence point to be 23.5, the pKa to be 4.25 and the Ka to be 5.62 x 10^-5. I just need to figure out the unknown concentration of the weak acid.
what is the value of equilibrium constant Kp if the total pressure is 11 atm?
The gas is heated to 675. K at a constant external pressure of 1.00 bar. b. The gas is heated to 675. K at a constant volume corresponding to the initial volume. c. The gas undergoes a reversible isothermal expansion at 310. K until the pressure i..
A student weighed 0.4521 g of sodium oxalate and dissolved in 50 mL of distilled water and 10 mL of 4.0M H2SO4. The solution was titrated with 58 mL of KMnO4, what was the concentration of KMnO4.
