I hope this helps. Just let me know if you would like more examples. Well supposedly my letter didn t arrive to you successfully therefore, I ll try to remember what I wrote and be brief. I wanted to inquire about two subjects pertaining to my Math class and hopefully your knowledge and experience in your workplace. We re looking forward to hearing from you again.
Chemists use pH as a measure of how acidic or basic a compound is.
The scale for pH is from 1 to 14 where pH 1 is very acidic and pH 7 is neutral like water. Some compounds keep their hydrogen ions so they aren t very acidic even though lots of the compound is in the water. Other compounds completely break apart like hydrochloric acid and sulfuric acid and so are quite acidic for the same amount of compound in the water. It also matters how much of the compound is in the water. It may be very dilute and not so acidic.
