Question

There is ____________ times as much OH⁻ in household ammonia as there is in seawater.

Answer 1

Explanation:

one thousand is answer

Answer 2

Answer:

The answer is 1000 times more hydroxyl ion in ammonia than in seawater.

Explanation:

The pH scale is a logarithmic scale depicting the concentration of – log H (concentration of Hydrogen ion) in a solution. This scale ranges from 0 to 14, where the neutral point is at 7.

At a neutral point, the concentration of Hydrogen ion and hydroxyl ion is same and equal. The pH of  seawater is 8. The pH of ammonia is 11. So, the number of times the hydroxyl ion is more in ammonia solution than in seawater is $10^{3}=1000$
