What is the H+ concentration for an aqueous solution with pOH = 3.58 at 25 degree C? Express your answer to two significant figures and include the appropriate units. Arrange the following aqueous solutions, all at 25 degree C, in order of decreasing acidity. Rank from most acidic to most basic. To rank items as equivalent, overlap them. At a certain temperature, the pH of a neutral solution is 7.21. What is the value of Kw, at that temperature? Express...
The boiling point of an aqueous 1.83 m (NH4)2SO4 (molar mass = 132.15 g/mol) solution is 102.5°C. Determine the value of the van't Hoff factor for this solute if the Kb for water is 0.512°C/m. Answer's 2.7 but I have no idea how to solve for this, can someone show me how to solve with LOTS of steps? Thanks.
