Explanation:
A.
Yes
B.
2KHP + Mg(OH)2 = 2KOH + Mg(HP)2
KHP is an acidic salt which reacts with Mg(OH)2 which is a base via double displacement/decomposition reaction.
C.
• One approach is to prepare the solution volumetrically using KHP crystals.
• Preparing 1 liter of 0.1 M KHP you would add 0.1 moles of KHP
Molar mass of KHP(C8H5KO4)
= (12*8) + (5*1) + 39 + (16*4)
= 204 g/mol
Number of moles = mass/molar mass
= 20.4/204
= 0.1 mol.
• This is added to a 1 liter volumetric flask, add deionized water until near the fill line, stopper and mix
D.
Number of moles = molar concentration * volume
= 0.025 * 0.100
= 0.0025 mol
Equation for the reaction:
Ba(OH)2 + 2KHP --> Ba(KP)2 + 2H2O
1 mole of Ba(OH)2 reacted with 2 moles of KHP. By stoichiometry,
Number of moles of Ba(OH)2 = 0.0025/2
= 0.00125 mol.
Molarity = number of moles/volume
= 0.00125/0.01
= 0.125 M of Ba(OH)2.

A solvent (from the Latin solvō, "I loosen, untie, I solve") is a substance that dissolves a solute (a chemically distinct liquid, solid or gas), resulting in a solution. A solvent is usually a liquid but can also be a solid or a gas. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature. Common uses for organic solvents are in dry cleaning (e.g., tetrachloroethylene), as paint thinners (e.g., toluene, turpentine), as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers (e.g., hexane, petrol ether), in detergents (citrus terpenes) and in perfumes (ethanol). Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within a cell. Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syntheses and purification processes.
