How much salt and how much water must be mixed to make 250g brine solution that is 50% salt by mass?
Concentration = (mass of solute/mass of solution) ×10050=(mass of solute/250gm)×100mass of solute = 250×50/100mass of solute = 125 gm mass of solution = mass of solute + mass of...

A blue Cu (II) cation salt solution was mixed with a green Ni (II) cation salt solution and an aqua colored solution resulted. Is this a chemical change or a physical change?
This is a physical change or a chemical change depending on the concrete example. For example, we can take Copper(II) sulfate - CuSO4 (gives a bright blue solution) and Nickel(II)...

Can salt be lost during evaporation because after evaporating H20 from NaCl i was left with 0.1g of salt but using the equation m=n×M there should of been 0.1255g of salt. How was the salt lost?
Sodium chloride is not decomposed when heated in water and you could not lose it that way. It is lost due to experimental error (maybe spillage of the solution)

will a precipitate occur if 250 ml of 1.5 x 10^.3 M NaCl is mixed with 250 mL of 2.0 x 10^.7 M AgNO3? Ksp of AgCl = 1.6 x 10^-10
The equation for the chemical reaction is NaCl(aq) + AgNO3(aq) = AgCl(s) + NaNO3(aq) Ksp = [Ag+] x [Cl-] = 1.6 x 10^-10 From the equation for Ksp: [Ag+] =...

A solution of salt solution is made by mixing 6.75 g of NaCl(s) in enough water to make exactly 750 mL of solution. What is the W/V percentage concentration of the solution?
Weight/Volume Percentage Concentration is a measurement of the concentration of a solution. Solubilities are sometimes given in units of grams of solute per 100 mL of water, that is, as...

A solution consisting of acid HA and salt KA If the pH value before adding salt is 3 and after adding salt 5 Calculate the concentration of the added acid
Your question is not clear and detailed. Well, I presume you meant a substance (salt) was added to an acid with the PH of 3. After adding it the PH...
