This page lists pH readings of various items relevant to bubble juice.
pH of Common Items[]
Pure water (no dissolved air): 7.0
Distilled water (pH somewhat acidic due to dissolved C02 from the atmosphere): 5.5-6.5
Edward's Readings[]
Readings - 2012/13[]
Here are various readings taken in 2012/13 with a pH meter that featured only single point calibration and plus/minus 0.2 accuracy though when checked with buffer fluid seemed generally to be plus/minus 0.1 Dawn Pro: 8.3 - 8.4
Club Soda: 5.2 (measured by Edward Spiegel at room temperature)
Edward's Tap Water (unfilitered): 8.9-9.7 (the tap water here sometimes has a surprisingly high pH. It is generally around 9.0 that 9.7 reading was surprising and may have been a sign that something was going on 'upstream')
Edward's Tap Water (Brita-filtered): 8.3
White Distilled Vinegar: 2.4-2.6
Bubble Juice and Deterent/Water Mixes[]
Various bubble juice readings taken by Edward. These are accurate to about +- 0.1 or 0.2
Uncle Bubble diluted at 9:1 with Edward's tap water: 7.8-8.0 (tap measured at 9.4)
Dawn Pro and Tap Water 50:1: 9.2 (on a day when Edward's tap water was measured at 9.7 with a calibrated pH meter)
Dawn Pro and Tap Water 50:1 + about 3.0 ml baking powder: 7.4
eGoo diluted at 15:1 with Crystal Springs mineral water: 8.5 (2014/04/16). add .51 grams (1/8 tsp) citric acid: 7.8. Add another 1/16 tsp: 7.6 (measured moments later)
eGoo diluted at 15:1: 8.3 (2013/10/03)
eGoo diluted at 15:1 with 0.18 grams citric acid added to 1 gallon: 8.1 (2013/10/03)
eGoo diluted at 15:1 with 0.57 grams citric acid added to 1 gallon: 7.6 (2013/10/03)
eGoo at 10:1 so heavily to dosed with baking powder that the juice was very milky and not transparent: 6.8 (2013 12 20)
500 grams tap water (pH: 9.3) + 27 grams Dawn Pro: 9.3
above with 1.25 ml vinegar: 8.3
additional 1.25 ml vinegar (total 2.5): 7.7
additional 2.5 ml vinegar (total 5.0): 6.2 (oops!)
BAD BUBBLE JUICE. diluted eGoo at 6.3 could barely make bubbles. The juice was fixed by raising pH with baking soda.
2014 July Measurements[]
These were made with the same pH meter (an inexpensive Chinese knockoff of the pH600).
Calibrated to 9.0 when measuring a 25:1 solution of distilled water and Dawn Manual Pot and Pan
Distilled White Vinegar: 2.4
60:1 distilled water/Dawn: 9.0
10:1 distilled water/Dawn Manual Pot and Pan (Dawn Pro): 8.8
5:1 dilution: 8.7
Dawn Manual Pot and Pan: 8.4-8.5 (it initially read 8.4 and after three minutes oscillated between 8.4 and 8.5)
