Problem- Calculate the pH and the pOH of an aqueous solution that is 0.025 M in HCl(aq) and 0.080 M in HBr(aq) at 25°C
Express your knowledge to solve the above question
When an additional mol of gas is added at constant temperature and volume to a flask containing 2.00 mol of gas at 25oC and 1.00 atm pressure, the pressure increases to 1.60 atm.
Determine the values for the enthalpy changes of formation of NAOH(aq), HCl (aq), KOH (s), and KOH (aq) in an appropriate work and state a balanced chemical equations corresponding to the values you just found.
