WHAT IS THE PH OF A PEACH WITH A -OH 3.2 X 10-11 M -OH?
You're given [OH-] = 3.2x10^-11, so to get pOH, take the neg. log. of that number: -log(3.2x10^-11) = 10.5, so the pH = 14-10.5=3.5.
What is the pH in waste water from pharmaceutical industries?
This depends on the technological process involved.
Is it normal for the Ph level of your salt water pool to be high after shocking it 30 minutes ago?
You are getting false readings because of the extreme high levels of chlor.

There is no real optimal pH. The best pH from rejection point of view for thin film composite membranes.
A solution is tested and found to have a pH of 1. The solution is?
One possibility is a 10% solution of hydrochloric acid.
What does the dental term 'carcinoma mucoepidermoid in glandular odontogeniccist of mandible' mean?
mucoepidermoid carcinoma is a form of cancer in the salivary glands. not sure about the rest.
What causes pH levels to drop in a swimming pool?
The fill water can be acidic. Hm, by "drop" you mean going from 7.8 to 6.8 or lower? If you use jumbo tabs that could be making your pH to lower to off scale readings. Note: if your test kit or solutions are old or have been left outside for even a day or less they could be rendered useless and give you false readings. The phenol red solution should be a strong redish color. The solution for chlorine readings should be clear not yellow - if yellow, then discard - no good. If you have just recently added stabilizer ( CYA ) you may get a temp. bad reading.
Check your water with a fresh or new test kit and solutions or take the water in for the pool store to test for comparisons. Take your test kit with you so that the store can compare your kit with theirs. Be sure to take the water sample from the pool just before you head for the store. If you take the sample from the pool in the morning and don't do to the store until that afternoon or the next day - that sample is useless to the store. The sample has to be fresh.
What are the colors of the pH scale when acids and bases are put with anthocyanin?
The colors of anthocyanins are:
- red to pink: pH under 7
- purple: neutral
- green to yellow: basic, pH over 7
- colorless: very basic
How might the pH level of the stomach inhibit growth of ingested bacteria?
Many bacteria doesn't support a very low pH.
Ants release a solution containing formic acid. The pH is of course under 7.
