Acids and bases

What is ph?

Ph is the measurement of how acidic and base water is

How do you measure ph?

The pH value can be measured using electrochemical measuring systems, litmus paper, or indicators and colorimeters.


What is the scale pH is measured on?


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


What ph level does water have is water acidic?

Neutral


What is the most acidic ph level?

0 is the most acidic level


What is the most basic ph level?

14 is the most alkaline level.


If there is more hydrogen ion it is acidic, and if there is more hydroxyl ions it means it is alkaline. 6 is the weakest acid and 8 is the weakest alkaline. Hydrochloric acid is the acid that helps digest the food that you eat.


To do the experiment, First, use a marker and label each item you will be testing. Measure about 4 or 5 drops of each item into the well plate and mark it for that item. Get a litmus paper and put both litmus paper blue and red at the same time, to see the result.
