Chemistry project acids and bases ph scale

Note: Do not completely submerge the probe. This behavior is unusual, and later on we will try to explain it. Strong Acids and Bases Acids with a low pH of around 1 are very reactive and can be dangerous.

Basic solutions, on the other hand, contain hydroxide ions OH.

ph definition

When he was a student, he studied the conductive properties of electrolytic solutions. Figure 10 - Soaking cards Figure 11 - Drying the cards.

For this purpose, the electrode of the meter is immersed in suitable buffer solutions with known pH.

ph scale examples

Acids have pH values under 7, and alkalis have pH values over 7. Pure water is usually pH 7.

ph scale chart

Our stomachs use hydrochloric acid to help digest foods.
