Calculate the volume (ml)of concentrated ammonia and the weight (gm) of ammonium chloride respectively to be taken to prepare 100 ml of buffer solution at a pH of 10 if the final concentration of the salt is 0.20 mol. Note that the molar concentration of concentrated ammonia is equal to 14.8 mol/liter, and that the pKb of ammonia is 4.76, and the molecular weight of ammonium :chloride 53.5 g/mole.lt is about
If enough of a monoprotic acid is dissolved in water to produce a 0.0124 M solution with a pH of 6.72, what is the equilibrium constant, p?a, for the acid? kindly consider the following when answering the question For weak acids that are so dilute or so weak that the pH of the solution lies between 6 and 7, the autoprotolysis of water must be taken into account when determining the p?a value. At equilibrium, there are four species in solution, the weak acid, HA, its conjugate, A−, H3O+, and OH−. Start by developing four equations that describe what is occurring in the solution at equilibrium.
A solution containing .30 M methylamine (CH3NH2) and .33 M methylamonium chloride (CH3NH3Cl) has a pH of 10.60. Calculate Kb for the methylamine from this information
Like any equilibrium constant, Kᵥᵥ changes with tempera-ture. (a) Given that autoionization is endothermic, how does Kᵥᵥ change with rising T? Explain with a reaction that includes heatas reactant or product. (b) In many medical applications, the value of Kᵥᵥ at 37°C (body temperature) may be more appropri-ate than the value at 25°C, 1.0X10⁻¹⁴. The pH of pure water at 37°C is 6.80. Calculate Kᵥᵥ, pOH, and [OH] at this temperature.

Calculate the pKa of hydrofluoric acid (HF(aq)) and hydrogen cyanide (HCN). What would be the pH of a solution containing 5 mM HF? What would be the pH of a solution containing 5 mM HCN?You do not need concentrations. Standard Gribbs Free energy for HF is -296.8 and for HCN is 124.7 This calculation assumes the acid is completely dissociated. You need the pKa to figure out how much of the H+ is free. This was all I was given. I do not know where to start, what I need, or what I need to calculate first. There are no other instructions or parts to this question. I'm at a loss, where do I begin?
