According to Google, using that very question –
a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid, and higher values more alkaline. The pH is equal to -log10 c, where c is the hydrogen ion concentration in moles per liter.
If you’ve ever had digestive troubles, heartburn or even allergies knowing what pH is and how it affects your diet and body is a crucial piece of information. Also, if you make home brewed drinks like beer, wine, or kombucha having an easy and inexpensive way to test the pH is invaluable. This is necessary for fermenting vegetables as well. You could wing it, but it’s always best for safety to have the proper testing equipment available.
The pH Dips strips I received for review come in a solid plastic case with a snap on lid. This prevents them from being exposed to humidity unnecessarily. The lid does lock on fairly tight so be careful you don’t spill the strips when you open the container. It’s nice to have the comparison chart visible through the clear plastic box instead of as a separate booklet. This makes it easy to reference.
pH Dips are super fast and give you results – they display complex chemistry with a beautiful colorful matrix – these strips get it done. Each test strip can indicate the pH of a liquid or gel, even solutions with light color. Each box contains 100 test strips and each strip may be used one time. Each of four colored pads on the business end of the strip will reliably change color depending upon the pH of the liquid. Comparing to the color chart is fun and easy. This is a simple clean method for determining the pH quickly and accurately; as well, the box is a perfect size. The instructions are helpful and informative; these strips have so many applications, they are truly universal, testing from 0 to 14.
The strips change color immediately upon immersion in the liquid. Make sure you have the container handy for comparison nearby as well as a napkin or towel to soak up any excess liquid or drips. I used the strips I received for review mainly for testing the pH of kombucha. “As the Kombucha culture digests the sugar it produces a range of organic acids like glucuronic acid, gluconic acid, lactic acid, acetic acid, butyric acid, malic acid and usnic acid; vitamins, particularly B vitamins and vitamin C; as well as amino acids, enzymes”*. Kombucha should have a pH between 2 and 3 before it’s bottled or consumed. At this level most of the sugar has been consumed by the SCOBY and there is plenty of acid which helps inhibit bad bacterial growth and makes the brew somewhat resistant to microbial invasion. You can use these pH Dips testing strips to test any liquid, gel or fluid.
I received a complimentary item for the purposes of review.
