Answer:
pH 12
Explanation:
Hydrogen ion concentration is usually expressed in terms of pH, which is the logarithm of the reciprocal of the hydrogen ion concentration. The molar concentration of dissolved hydrogen ions in solution is a measure of acidity. The greater the concentration of hydrogen ions in solution, the greater its acidity. This concentration can range over a tremendous range, from 10^-1 M to 10^-14 M. A convenient system of expressing this range of concentrations is the pH scale which means power of hydrogen.
The higher the pH value the lesser the hydrogen ion concentration and the greater the hydroxide ion concentration. A pH value of 1-6 indicates acidity (high hydrogen ion concentration) a pH of 7 indicates neutrality while a pH of 8-12 indicates alkalinity (high hydroxide ion concentration).

Answer:
The differences in atmospheric pressure generate winds.
Explanation:
At the Equator, the sun warms the water and land more than it does the rest of the world. Warm equatorial air rises higher into the atmospher and migrates towards the poles. The complex relationships between fronts cause different types of winds and weather patterns.
I hope this helps :)
