Answer:
10
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
Thus, from the formula, more the concentration of the hydrogen ions or more the acidic the solution is, the less is the pH value of the solution.
Thus, solution with pH = 3 will be more acidic than solution with pH =4
Thus, concentration of the [H⁺] when pH =3
3 = - log [H⁺]
[H⁺] = 10⁻³ M
For pH = 4, [H⁺] = 10⁻⁴ M
<u>hence, pH = 3 is 10 times more acidic than pH = 4</u>
Answer:
Scientist used models to explain and predict the behavior of real object or system
Scale and measuring tape.
To determine the mass and volume, you can find the density. The block will float if its density is less than that of water.
This is due to the solubility of CO₂ in blood is more than the solubility of Oxygen in blood
