**The strength of an acid or base in a solution is measured on a scale called a pH scale. **The pH scale is a measure of the hydrogen ion concentration. It spans from 0 to 14 with the middle point (pH 7) being neutral (neither acidic or basic). Any pH number greater than 7 is considered a base and any pH number less than 7 is considered an acid.
Current color shows the pH around 5.5. Solid carbon dioxide (dry ice) is added. The CO dissolves and. reacts to form carbonic acid. This lowers the pH of the solution as shown by the color change of the universal indicator. The pH is now around 4.0.
The pH scale is used to classify substances as acids and bases. The scale goes from 0 to 14. Things that are acids have a pH number that is less than 7. The lower the number, the stronger the acid. Bases have pH values higher than 7. The higher the number, the stronger the base. An example of a strong base is drain cleaner or oven cleaner. Both ...
On the construction paper, NEATLY draw a pH scale. Scale the line from 0 to 14 with a mark for each number. Cut out words & paste the labels in correct areas of pH scale. Color & Label the pH on the picture. Cut out & paste in the correct sections of the pH scale.
pH is a measure of how acidic or basic a substance is. It takes a numerical value between 0 and 14 that measures the relative amount of free hydrogen and hydroxyl ions in water. Water having more hydrogen ion concentration than hydroxyl is acidic.
