The pH scale is used to determine how acidic or alkaline different solutions are. The scale goes from 0 to 14. Right in the middle is 7, considered to be neutral. Anything below 7 is acidic.
How can you measure pH?
There are two methods for measuring pH: colorimetric methods using indicator solutions or papers, and the more accurate electrochemical methods using electrodes and a millivoltmeter (pH meter).
Why do we check pH of products?
Pharmaceutical manufacturers measure pH in order to check chemical reactions in production. Speed of reactions depends on the pH of a solution, and the end point of a reaction can be estimated by knowing the pH. If there is big difference in pH between skin and cosmetic products, the results could be disastrous.

What is neutral pH?
pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
What are pH neutral cleaners?
Simply put, a pH neutral cleaner is one that has a neutral pH level. While a truly neutral solution has a pH level of 7, pH neutral cleaners are typically considered to have a pH level between 6 and 8. Considering pH levels when selecting commercial cleaning products is critical to avoid damaging surfaces.
Is washing up liquid pH neutral?
– Washing up liquid (pH 7-8): The neutrality makes this cleaning product ideal for daily cleaning. Most surfaces will not be damaged and it can be used in hundred places around the house, not only to do the washing up. As it is at the end of the pH scale, you have to be careful when using it.

What is the most accurate way to measure pH?
pH meters are the most accurate type of measurement and are widely used. Pocket-sized meters called testers are small, easy to use for fieldwork and relatively low cost. One step above the testers is handheld, portable meters.
How can pH be measured GCSE?

The lower the pH reading, the more acid the food. In order to preserve foods with acidity, the regulation requires the pH to be 4.6 or below. At these levels, toxins formed by the deadly organism causing botulism are inhibited. We refer to foods which have readings greater than pH 4.6 as low-acid foods.
Why is it important to test the pH of the products while using the chemical preservatives?
Among the reasons for measuring pH in food processing include: To produce products with consistent well defined properties. To efficiently produce products at optimal cost. To avoid causing health problems to consumers.
Why is pH important in industry?
