Answer to Question #67992 in Molecular Biology for Pinks

Question

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

Answer 1

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
