The normal range of the pH of blood is between 7.35 and 7.45; variations beyond this range have significant health implications.
patriot [66]

Answer:

The hydrogen ion concentrations associated with these pH value 7.35 is 4.5\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.45 is 3.6\times 10^{-8} M.

Explanation:

To calculate the pH of the solution, we use the equation:

pH=-\log[H^+]

We are given:

1) pH = 7.35

Putting values in above equation, we get:

7.35=-\log[H^+]

[H^+]=4.467\times 10^{-8} M\approx 4.5\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.35 is 4.5\times 10^{-8} M

2) pH = 7.45

Putting values in above equation, we get:

7.45=-\log[H^+]

[H^+]=3.548\times 10^{-8}M \approx 3.6\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.45 is 3.6\times 10^{-8} M.

Which of these mixtures would best be separated through distillation
Andrew [12]

Answer: Water and acetone

Explanation: you will find that the water and the soil are polar opposite, while the principal component of the water are Hydrogen and Oxygen, in the acetone you will find a change of carbon, the components from each molecule confer to each one specific physical properties for example the boiling point, and the distillation is a physical separation based on the boiling point.

then you can find the boiling point of the water in 100 °C, and the boiling point of the acetone is 56 °C, this give as a difference of 44 °C,

then while the acetone is boiling the water is liquid state, and this give us the opportunity to the separate the acetone in gas state by condensation after the boiling.
