Considering how the conjugate base of a strong acid has no measurable strength, does that mean that the conjugate acid of a strong base has no measurable strength as well?
what is the molarity of HCl in a solution prepaired by dissolving 18.25 gm HCl in 200 gm ethanol, if the density of solution is 0.86 gm per mm
Nitric acid is gernerated by the action of sulfuric acid on sodium nitrate. Nitrous acid is prepared by the action of hydrochloric acid on sodium nitrite. Why is nitrous acid prepared in situ rather than obtained from the reagent self.
In the following conditions calculate the moles of hydrogen and the pressure in each flask where the volume is negligible. Each flask is originally 275K with .455 mols of hydrogen gas and .7atm of pressure. Then one flask is heated to 500K while t..
