25 ml of 0.20 M NaBr is mixed with 45 ml of 0.30 KCl. Determine the molarity of the ions. Given-- Na+1=0.24M SO4-2=0.12M Mg+2=0.24M Br-1=0.48M 2. 24...

  1. 25 ml of 0.20 M NaBr is mixed with 45 ml of 0.30 KCl. Determine the molarity of the ions.

Given-- Na+1=0.24M

SO4-2=0.12M

Mg+2=0.24M

Br-1=0.48M

2. 24 ml of 0.16 M NaCl is mixed with 36 ml of 0.25 M BaCl2. Determine the molarity of the ions.

Given- Na+1= 0.064M

cl-1=036M

ba+2= 0.15M

3. If 25.0 ml of 0.800M Ca(NO3)2 is mixed with 400 ml of 0.600M Na2CO3

a. Calculate the moles of each ion added to te mixture.

b. Determine which ion limits the amount of precipitate formed and determine how many moles of the precipitate will form.

c. Determine the molarity of each in in solution after the precipitate has formed and settled out of the mixture.

Top Answer

1. The total volume of the mixture is V = 25 ml + 45 mL = 70 mL NaBr dissociate to Na + and Br - ions, so we have [Na + ] =... View the full answer
