Suppose you wanted to produce an aqueous solution of pH 8.75 by dissolving potassium nitrate in water what is the molarity?

Not likely. Potassium nitrate, KNO3 is the salt of a strong acid (HNO3) and a strong base (KOH). Thus, the pH of a solution of KNO3 will be very close to pH=7, depending really on the pH of the water used to make the solution. There is no way to get it to pH = 8.75. You'd need to used something like potassium acetate, the salt of a strong base and a weak acid.

Which potassium salt K is the most soluble at 40 C and 80 C?
I suppose that this compound is potassium carbonate, K2CO3.
What is the resulting molarity of a solution made by mixing equal volumes of solutions of HCl and NaOH each of molarity 1M?
As a thought experiment - suppose you mixed one liter of 1M HCl with 1 liter of 1M NaOH. The resulting solution (neglecting any density changes associated with mixing) would contain 2 liters with 1 mole of Cl- and 1 mole of Na+ with the balance being water (the H+ from the HCl and the OH- from the NaOH would just become part of the water). This would give you a 0.5 M solution of NaCl.
Suppose you were dissolving a metal such as zinc with hcl. How would the particle size of the zinc affect the rate of its dissolution?
The bigger the particle the lesser the dissolution.
Titration of an acid with a standard base?
Suppose you have titration solution do you know if you have too much standard base?
How many moles of NF are dissolved in 4 L of a solution that has a concentration of 4 M?
Theoretically 16 moles but nitrogen monofluoride is unstable and I suppose that this solution cannot be prepared.
Equal moles of H2O and NaCl are present in a solution Hence molarity of NaCl is?
I suppose that this situation is not possible.
How does the energy required for dissolving the solute compare with the energy released If a solution process is exothermic?
I suppose that these are synonyms.
What is the term for Heat taken or released in a dissolving process?
I suppose that these are synonyms.
What is the temperature at which crystals will start to form when a solution of 30 g of potassium nitrate in 100 g of cooled water?
I suppose that this temperature is approx. 5 oC.
How do you graph a solution set?
just add all the numbers I suppose and the number you get is the number you graph the solution. I suppose.

Why is it thermodynamically possible for some ionic solids to dissolve even though the solution process is endothermic?
Even though the process is endothermic, the dissolving of the solid increases the entropy enough to more than compensate for the drop in temperature.
Suppose you were dissolving a metal such as zinc with hcl. How would the particle size of the zinc affect the rate of its dissolution?
The bigger the particle the lesser the dissolution.
Is it possible for oil to have a solution in solid or gaseous form?
I suppose that is not possible.
What is the name of the process salt solution?
I suppose that you think to the dissolution of salt in water.
Why is potassium permanganate used in titration experiment despite being a secondary standard solution?
kmno4 is very good oxidizing agent. that means it is easily reduced by any other reagent. so it can't be considered as primary standard as its concentration changes upon free leaving
