On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, 3) and (3, 4).
Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 2) and (1, 1). Everything to the right of the line is shaded. Which system of linear inequalities is represented by the graph?
PH can be calculated using the following equation pH = -log [H₃O⁺] for apple juice the hydronium /hydrogen ion concentration is 0.0003 pH = -log (0.0003) pH = 3.5 correct answer is C
For ammonia pH = -log (3.1 x 10⁻⁹) pH = 8.5 answer should be 8.5
