Consider two solutions, solution a and solution
Ronch [10]
Answer is: solution A has 2,57 time greater pH value than solution B.<span>
</span>Concentration of [H⁺] in solution A is than 370x.
pH = -log[H⁺].
pH(solution A) = -log(370x).
pH(solution b) = -log(x).
pH(solution A) / pH(solution B) = -log(370x) / -log(x).
pH(solution A) / pH(solution B) = 2,57.

If 0.089 grams of KI is dissolved in 500g of H2O, what is the concentration of the resulting solution in parts per million?
frez [133]

Answer:

The concentration of the resulting solution in parts per million is 177.97

Explanation:

Parts per million (ppm), is a unit of measure for concentration that refers to the number of units of the substance per million units of the set.

The concentration in parts per million expressed in mass / mass is calculated by dividing the mass of the solute (ms) by the mass of the solution (md, sum of the mass of the solute and the mass of the solvent), both expressed in the same unit and multiplied by 10⁶ (1 million).

ppm=\frac{ms}{md} *10^{6}

So, being:

  • ms: 0.089 grams of KI
  • md: 0.089 grams of KI + 500 grams of H₂O= 500.089 grams

Replacing:

ppm=\frac{0.089 grams}{500.089 grams}*10^{6}

ppm= 177.97

<u><em>The concentration of the resulting solution in parts per million is 177.97</em></u>
