Problem- A 25 mL sample of 0.110 M solution of acetic acid is titrated with a 0.138 M solution of NaOH. Calculate the pH of the tritration mixture after 10.0 and 20.0 mL of base have been added. (The Ka for acetic acid is 1.76x10^-5)
I am stuck in between this question please help me out
The standard heat of formation \Delta H^\circ _{\rm f} is defined as the enthalpy change for the formation of one mole of substance from its constituent elements in their standard states. Thus, elements in their standard
A 0.1000 M NaOH solution was employed to titrate a 25.00-mL solution that contains 0.1000 M HCL and 0.0500 M HOAc. Find out the pH of the solution after 27.50mL of NaOH is added. Ka HOAc = 1.75*10-5.
