How am I supposed to know >:(
Answer:
pH = 6.5
Explanation:
Given data:
pH of substance = ?
[OH⁻] concentration = 3.2×10⁻⁸
Solution:
pOH = -log[OH⁻]
pOH = -log[3.2×10⁻⁸]
pOH = 7.5
we know that,
pH + pOH = 14
pH = 14- pOH
pH = 14 - 7.5
pH = 6.5
Answer:
Explanation:
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. Assume that you have to identify an unknown metal.
