Answer:
Scientific ideas are changed when better ones are found.
Explanation:
That acid rain has lowered the ph of a particular lake to ph 5.0. the hydroxide ion concentration of this lake is
1 × 10^-9 mol of hydroxide ions per liter of lake water
pH + pOH = 14
pOH = 14 - 5
pOH = 9.00
pOH = -log [OH⁻]
[OH⁻] = 10^-pOH
[OH⁻] = 
mol
Therefore,
the hydroxide ion concentration of this lake is 1 × 10^-9 mol
