pH
The pH scale determines whether a substance is acidic, basic, or neutral. It measures acidity or basicity on a scale from 0 to 14.
A pH of 7 is neutral. For example, distilled water is neither acidic nor basic.
Acids have a pH lower than 7. Stronger acids have a pH close to 0, while weaker acids have a pH around 5.
Bases have a pH above 7. Strong bases have a pH near 14, while weaker bases have a pH around 9.
Let’s test how pH strips change color with different substances.
Take one glass each of lemon juice, baking soda solution, and distilled water.
Next, dip a pH strip into each glass.
Lemon juice turns the strip orange, indicating a pH of 2 and a strong acidic nature.
The baking soda solution turns the strip light blue, indicating a pH of around 9, which is slightly basic.
Distilled water turns the strip green, confirming a neutral pH of 7, which means it is neither acidic nor basic.
pH
pH measures how acidic or basic a solution is, ranging from 0 to 14. A low pH (0-6) indicates an acidic solution, 7 is neutral, and a high pH (8-14)…
