There's a total of 3 colors, the percent will add up to 100%
100%-50%(red)= 50%

Answer:
x = 1 x 10⁻²
Explanation:
Since the pH is the same in both cases, the two expressions for pH can be set equal to each other:
pH = 4 + log(x) = -log[H⁺]
The hydrogen ion concentration ([H⁺]) is 0.01 M, so this value can be substituted in the equation:
4 + log(x) = -log(0.01)
4 + log(x) = 2
log(x) = -2
x = 10⁻²
Non polarcompound I think so
