Freezing PH'd water will melt at the same PH?

I would assume so as long as there is nothing to alter the ph? it may warrant an experiment. There are non ice, ice cubes https://www.amazon.com/Stainless-reu...a-767868443977

Water temperature changes will change the PH of the water. When the water is frozen it’s a different PH than when it’s not, no matter what adjustment you made prior to freezing. Same issue when the ice melts. It’s a veritable that would require extreme controls to regulate.

If you check the pH, and later the water is frozen and then later thaw my guess is the pH will be the same. water temperature does effect the pH, but if measuring the water at the same temp after thawing should be the same. give it the old experiment.

So here it is. Kind of. I started with four ounces of water in three cups. One cup straight from the tap, one at a 6 pH and the third at 5 pH.

Once frozen, I removed the cups from the freezer and let them thaw at room temp.

Now, there is some variance at play. I tried wiping my meters off before dipping in the other cups. I also should've let them cups sit until room temp and taken the readings again but it slipped my mind. Anyway, take this little test with a grain of salt. I kind of want to try this again just to make sure everything was correct. I calibrated my pH tester before the test but I still feel uneasy with the results. I can deal with that pH swing for my little experiment. If that works out, I'll update this thread.
