The pH of a solution is 10. What is its OH- concentration

1 x 10∧-4

Explanation:

In other for us to get the OH- concentration,we must first get the pOH.

pH + pOH = 14

pOH = 14  - pH;  14 - 10 = 4

From the formular for finding pOH, we know; pOH= - Log [ OH-]

∴  [ OH-] = Anti -log of 4

              =   10∧-4 =  0.0001

              = 1  x 10∧-4

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
