WCK asked:
The problem is Does temperature affect the pH of orange juice?
Can I use regular pH testing strips for my pool to test this?
I’m using 3 temperatures: Chilled in refrigerator, Room temperature and heated, but how should I heat the orange juice?
I want to do this in an organized, accurate way.
Thank You!!

Well you could leave it in the sun BUT if you live in england (probably more south-west like me) you would notice thatit has been raining for ages lol. But that would probably be the best way. Make sure you leave each of them in one place for the same amount of time or it wont be a fair test ^^.

Pool strips are typically meant to test chlorine levels in the water (plus some other chemicals) and generally only test pH levels from 4-10. Orange juice is more acidic than that, typically around 3 and with temperature change, can increase (lower number). So you may need to buy litmus paper strips specially for this.
As for heating or cooling tests, it is important to ensure uniform temperature for the juice. So be sure to stir is well before you make temperature and pH measurements. You can heat OJ simply by putting it in a pot and slowly heating it on your kitchen gas range
Unless you want to measure in small temperature increments, the kitchen approach should work – if you just want to do chilled, room and high. For more accurate heating, you could use a controllable heater of some sorts… do you have access to your school Chemistry lab? Another way to slow down temperature rise at home would be to heat water in a pot, put the orange juice in another smaller pot and immerse it in this outer pot (make sure the bottoms are not sticking, if you want more control, by putting a small bottle cap or ceramic piece under the smaller pot)
the ph miracle balance your diet
pH strips: no, you cannot use normal pH strips, you will need to make your own, but don’t worry, it’s cheap and easy. Here’s what you do: take a normal tortilla, cut it into strips of desired length, then put a thin layer of Elmer’s glue on one side of the tortilla strip, then put the strips on a pan so that they aren’t touching each other. Put the strips in a heated oven (around 250 Fahrenheit) and let bake until crisp, but not brown. After baking period, you now have your own pH strips. If you dip the strip in a solution and the strip comes out green, then the solution is basic, if it comes out orange, then the solution is acidic.
As far as heating the orange juice goes, I’ve got no clue.
Hope that helps
pool test kits vary, the acidity of drinking water and oranges are close, so test the ph of both, if there is a distinct difference, use the kit you have.
you’ll also need a thermometer, digital is best, but anything with a range of about 40 degF to 212 degF should do ok ( 212degF is high, you can use a lower one, but they can blow up if you go over the max temp, be very careful). test the ph 3 times per temperature and take an average of the three readings, record all readings, this should be a safe bet
