ACIDS AND BASES

ACIDS

• There is a PH value and if the value is smaller than 7 that means that object is acid.
• It tastes sour.
• They have more protons than bases.
• They are more positive charged.

BASES

• When the PH value that is bigger than 7 that is bases.
• Felt slippery.
• They are more negative charged.
• They have less protons than acids.

QUESTIONS OF THE DAY

• What is the ph scale for water?

THE ANSWER

• 7
• Because the water is neutral.

THE TOOL THAT WE CAN USE FOR MEASURING THE PH VALUE OF A SOLUTION

• The PH paper.
• That is like a strip of paper that can change colors when we dip the paper in the solution, then we can know is that solution acids or bases.

DIFFERENT COLORS MEANS DIFFERENT

• Red means the solution is strong acid.
• Orange means it is weak acid.
• Green is neutral.
• Blue is weak base.
• Purple is strong bases.
