Product Details

Application:

The rate and outcome of chemical reactions taking place in water often depends on the acidity of the water, and it is therefore useful to know the acidity of the water, typically measured by means of a pH meter.Knowledge of pH is useful or critical in many situations, including chemical laboratory analyses. pH meters are used for soil measurements in agriculturewater quality for municipal water supplies, swimming poolsenvironmental remediationbrewing of wine or beer; manufacturing, healthcare and clinical applications such as blood chemistry; and many other applications

The pH scale 
The values for pH make more sense when compared with that of known substances. Note that the pH scale is logarithmic and that each next value contains ten times less hydrogen ions. A pH=0 contains the most, and is highly acidic.

10.1 N HCl, hydrochloric acid (1.1)
2Lemon juice. Vinegar (2.4-3.4)
3wine (3.5-3.7)
4Orange juice. Apple juice (3.8). Beer. Tomatoes.
5Cottage cheese. Black coffee. Rain water 5.6.
