Answer:
pH = 4.7
Explanation:
The pH is a measurement of acidity using the concentration of hydrogen ions (H⁺) in a solution. Therefore, before you can find the pH, you need to determine the concentration (M) of H⁺ in the solution. This can be done by multiplying the molarity of the solution by the amount of H⁺ in the solution.
1 mole H₂SO₄ = 2 moles H⁺ and 1 mole SO₄⁻
1.0 x 10⁻⁵ M H₂SO₄ 2 moles H⁺
----------------------------- x ---------------------- = 2.0 x 10⁻⁵ M H⁺
1 mole H₂SO₄
To find the pH, you need to use the following equation:
pH = -log[H⁺]
Since you calculated the hydrogen concentration ([H⁺]) in the previous step, you can plug it into the equation and solve.
pH = -log[H⁺]
pH = -log[2.0 x 10⁻⁵]
pH = 4.7
It is tasteless and colorless.
A hypothesis is a working explanation, where a theory is a well established explanation. So really hypothesis is a more of a "guess and check" "work in progress" and a theory is like a summary of overall explanation of the observed behavior. hope this helps
