How Does Temperature Affect pH?

Temperature plays a significant role on pH measurements. As the temperature rises, molecular vibrations increase which results in the ability of water to ionise and form more  hydrogen ions. As a result, the pH will drop. The dissociation of water into hydrogen and hydroxide ion can be represented as: H2O (l) ⇌ H+ (aq) + […] ... Read More

What is a Buffer and how does it work?

A buffer is an aqueous solution that can resist significant changes in pH levels upon the addition of small amount of acid or alkali. Each buffer is characterized by a set ‘capacity’ which is defined as the quantity of strong acid or base that must be added to change the pH of one liter of […] ... Read More

What is the correct way to store a pH electrode?

Correct storage of your pH probes can substantially increase the longevity of the probe saving you time, effort, and money. Here are a few points on how to get the most out of your probes. Firstly, you should make sure you always keep your pH electrode moist, the best solution to submerge the probe for […] ... Read More

Why doesn’t a pH Sensor display pH 7 in deionised or distilled water?

Have you ever wondered why you can’t get a consistent pH reading on your distilled or deionised water? Here is why… The electrodes of a pH meter will not give accurate values in pure water because distilled and deionised water do not have enough ions for the electrode to function accurately. The readings will most […] ... Read More

What is pH?

Most living things depend on a proper pH level to sustain life. Your body is continually working to maintain the appropriate pHs. The blood flowing through our veins must have a pH between 7.35 and 7.45. Exceeding this range by as little as 1/10th of a pH value could prove fatal. pH is a measure of acids […] ... Read More

Measurement of pH in Plant Tissue

Measurement of pH in Plant Tissue It is often necessary to measure the pH of plant tissue to determine plant health. Where pH values are above 6.4, plants can be prone to insect attacks and specific diseases, thus an optimal pH of 6.4 is desired. Whilst laboratory soil and tissue tests are beneficial tools, they […] ... Read More

A Guide to Taking Proper Care of Your pH Electrodes

If you measure the pH of solutions on a regular basis, you would know it is quite a tedious task. You have to stand there and adjust the pH of the buffer, add acid or alkali drop by drop till you get the right pH. While pH-ing can be boring, it is essential that the […] ... Read More

Why use a non-bleeding pH test strip?

What exactly does it mean when we see non-bleeding test strips? Unlike common indicator papers, non-bleed is a patented technology whereby the test strips are chemically bound to the test pads. This safely prevents the dyes from bleeding into the sample which prevents contamination and allows you to continue with further analysis of the solution. […] ... Read More
