So I was just watching a video by The Omar Gosh Vlogs. The latest video on this channel is of a toxic pit. This pit is known as the Berkeley Pit in Butte Montana. It is filled with toxic water. In the video, it is said that the pH of the water is the same as stomach acid. Usually, the pH of drinking water is 6.5-8.5 and the pH of stomach acid is 1.5 to 3.5. Apparently the pit was a copper mine. I thought this was pretty cool. #Youtube
