Q4 - ETCHED IN ACID
B - The newspapers are continuously telling us about "litmus tests", which are not really for acids or bases, but are absolute political pre-conditions of various sorts.
Not directly relevantly.....
This interspecies household product can be made of old newspapers, or can come mixed with a bit of litmus.
G - All those female docs who dominate the TV clinical scene hopefully will still remember that on the 0-14 point pH scale, normal human blood comes in at
1 - pH = 5.40
2 - pH = 7.40
3 - pH = 9.40
4 - pH = 11.40
I am gonna save Q5 for the future. I like it too much.
For fun:ONe The two questions I did not get to post: May 2
