      Acid rain is about 100 times less acidic than Coca-Cola. Coca-Cola is not strong enough to dissolve skin. Therefore, acid rain is far too weak to dissolve human skin.

      Acid rain is pretty harmful when inhaling it can lead to illnesses like asthma or chronic bronchitis (chronic bronchitis affects the airways in your lungs and makes it inflamed. 'Causes severe coughing spells that bring up mucus, wheezing, chest pain and shortness of breath.)

      Inhaling acid rain can cause a reduce heart function, leading to heart attacks and even death.

      So yeah, diffidently don't drink/inhale acid rain.
      _______

      If you're wondering acid rain is made from natural causes, like volcanic eruptions. Though it's more commonly made due to human activities. :(

      Edit: OH! I just searched this up but apparently acid rain doesn't only form in the shape of rain, it can come in many forms: rain, snow, sleet, hail, and fog!

    Do you know the smaller the number on the ph scale the more acidic and the strongest acid (fluoroantimonic acid) has a ph scale of -31.3!

      Yes. with let's say a small rock, sure it can take a while to break it down, but eventually the small rock will break but it won't take as long as it would for a big rock. because the big rock has more volume than the small rock, the water has more atoms to break down for the big rock to be broken.

    Why does acid rain exist? If it was raining acid, would I be dissolved, or would I just get a lot of acid burns?

      Acid Rain exists because we release harmful greenhouse gases which change the properties of the water. I'm pretty sure you would be perfectly fine if you stayed inside if it was raining acid.
