What is the final concentration of cl ion when 250 ml of 020 M cacl2 solution is mixed with 250 ml of 040 M kcl solution?
Start with CaCl2. 250ml of 0.20M solution will give (0.2/1000)*250 moles
= 0.05 moles.
However, CaCl2--> Ca2+ + 2Cl- (1:2 reaction) so 0.05moles of CaCl2 will give 2* 0.05 moles cl ions =0.1moles.
KCl will give (0.4/1000)* 250 moles
=0.1 moles
Since KCl--> K+ + Cl- (1:1 reaction) so 0.1 moles KCl will give 0.1 moles Cl ions.
Add the 2 together so 0.1moles + 0.1 moles = 0.2 moles in total.
What else can I help you with?
1 mL of 10 mM NaCl solution was mixed with 4 mL of 0.05 M CaCl2 solution The final concentration of Cl- is?
The initial moles of NaCl in 1 mL of 10 mM solution is 10 µmol. The initial moles of Cl- in 4 mL of 0.05 M CaCl2 solution is 0.2 µmol. Therefore, the total moles of Cl- after mixing is 10.2 µmol. The final concentration of Cl- is 2.55 mM.
What does CaCl2 plus MgSO4 make?
When CaCl2 and MgSO4 are mixed, they will not form a new compound. Instead, they will remain as two separate compounds in the solution.
Barium chloride is added to potassium chloride What will be colour of the final solution?
The final solution color will depend on the concentration of barium chloride and potassium chloride. However, in general, barium chloride is white and potassium chloride is colorless, so the final solution will likely appear white or colorless.
Can solution have a negative concentration?
Concentration is the measure of how much of a given substrate is mixed with another substance,so it can never be negative.
Is a solution evenly or unevenly distributed?
A solution is evenly distributed when the solute is uniformly mixed with the solvent throughout the entire mixture. This results in a homogeneous solution where the concentration of the solute is the same in all parts of the solution. Uneven distribution would mean that the solute is not uniformly mixed, resulting in a heterogeneous solution.
What is the final concentration of cl- ion when 250 ml of 0.20 M cacl2 solution is mixed with 250 ml of 0.40 M kcl solution?
To find the final concentration of Cl- ions, first calculate the moles of Cl- ions from each solution. Then add the moles of Cl- ions from both solutions and divide by the total volume of the mixed solution (500 ml) to get the final concentration. Using the formula C1V1 = C2V2 where C represents concentration and V represents volume, you can determine the moles of Cl- ions from each solution.
How do you calculate the concentration of two mixed solutions?
calculate final molarity of the solution if 11ml of 5m solution is made up to 20ml

How do you make a 0.1 molar solution if you had a 1.0 molar solution to start with?
To make a 0.1 molar solution from a 1.0 molar solution, you would dilute the original solution by a factor of 10. For example, you could mix 1 part of the 1.0 molar solution with 9 parts of solvent (like water) to achieve a final concentration of 0.1 molar.
Two clear solutions are placed in separate beakers the first solution as a pH of 4 and the pH of the second is unknown if the two solutions are mixed and the resulting pH is 5 the second solution must?
The pH of the second solution must be neutral (pH 7), as mixing an acidic solution (pH 4) with a basic solution (pH 7) would result in a pH closer to 7. This indicates that the pH of the unknown solution is around 7 to yield a final pH of 5 when mixed with the pH 4 solution.
What happens when equal volumes of 0.20M CaCL2 an 0.20M Pb(NO3)2 are mixed?
CaCl2(aq) + Pb(NO3)2(aq) ===> Ca(NO3)2(aq) + PbCl2(s) so a precipitate of PbCl2 (lead chloride) will form. The fact that equal volumes of 0.2 M are mixed indicates that all of the Pb^2+ and all of the Cl^- will precipitate out of solution leaving only Ca^2+ and NO3^- left in solution.
When an acid solution is mixed with a basic solution?
When an acid solution is mixed with a basic solution, there will be a neutralization reaction in which hydrogen ions from the acid will combine with hydroxide ions from the base, to form water.
What is the pH when you mix ph4 with ph8?
When mixing a solution at pH 4 with a solution at pH 8, the final pH will be between 4 and 8. The resulting pH will depend on the ratios of the two solutions being mixed. If equal volumes are mixed, then the final pH will likely be around 6.
