If Vinegar has pHof 3 and household ammonia pH of 11,then how many times different is the concentration?

Expert's answer

Each unit on pH scale corresponds to 10 fold difference.

There are 8 units between ammonia and vinegar (11-3=8)

Thus, ammonia has 10^8 times fewer hydrogen ions.

10^8= 100000000 or 10 million
