In a recrystallization from boiling water of benzoic acid contaminated with acetanilide, you begin with an impure sample of 3.00 grams. If the % composition of the acetanilide impurity in the sample is 7.7 what is the minimum amount in mL of solvent (water) required for the recrystallization

- decrease the number of plants and animals living in the water.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
