Answer:
7.9 × 10⁻⁹ M
Explanation:
Step 1: Given data
pH of the ocean: 8.1
Step 2: Calculate the concentration of hydronium ions
We will use the definition of pH.
pH = -log [H⁺] = -log [H₃O⁺]
[H₃O⁺] = [H⁺] = antilog -pH
[H₃O⁺] = antilog -8.1 = 7.9 × 10⁻⁹ M
Since [H₃O⁺] < 10⁻⁷ M, the solution is basic.
Answer:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
