Question 1137085: How much 10% acid solution should be mixed
with 1 L of 25% acid solution to produce a solution that is 15% acid? Found 2 solutions by ikleyn, Alan3354:Answer by ikleyn(52781) (Show Source):
Let x = the volume of the 10% solution.
Then the basic equation is
0.1*x + 0.25*1 = 0.15(x+1)
saying that total volume of the pure acid in the mixture is the sum of the volumes of the pure acid in ingredients.
From the equation
x = = 2.
ANSWER. 2 liters of the 10% acid solution.
CHECK. 0.1*2 + 0.25*1 = 0.45 = 0.15*(2 + 1) = 0.15*3. ! Correct !
