Answer:
0.667 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 250 mL
Initial concentration (C₁) = 12 M
Final concentration (C₂) = 4.5 M
Final volume (V₂) =?
The final volume of the solution can be obtained by using the dilution formula as illustrated below:
C₁V₁ = C₂V₂
12 × 250 = 4.5 × V₂
3000 = 4.5 × V₂
Divide both side by 4.5
V₂ = 3000 / 4.5
V₂ = 667 mL
Finally, we shall convert 667 mL to L. This can be obtained as follow:
1000 mL = 1 L
Therefore,
667 mL = 667 mL × 1 L / 1000 mL
667 mL = 0.667 L
Thus, the volume of the solution prepared is 0.667 L
Answer:
it is perpendicular to the surfaces that rub together
When an acid is dissolved in water, by releasing protons into the solution, it lowers the pH.
What is pH?
The letters pH stand for the potential of hydrogen since pH is essentially a measurement of the number of hydrogen ions (i.e. protons) in a substance. The pH scale was created in 1923 by scientist Peter Lauritz Srensen. (1868-1969).
The pH of a solution is a key marker of its chemical makeup. The pH can have an impact on the biological processes that take place, the behavior of bacteria, and the behavior of chemicals.
