Acid and base are very crucial in our society. Without these two compounds, a variety of different product including paper, paint, detergent, soap, concrete wouldn’t exist.
Even numerous types of foods contain acid and base. It is also very important for a living organism. One of the examples is many plants and fish needed a certain range of acid and base to grow and survive.
While acid and base can be similar, there is a lot of differences between the two compounds. Both of these two compounds have the ability to conduct electricity. One of the differences in their properties. Acid taste sour when base tastes bitter. Acid produces positive hydrogen ions (H+) when dissolving in water. Whereas Base produces negative hydroxide ions (OH-). Another different is acid reacts with metal while the base doesn’t.
Different ranges of Acid and Base can be measured on a scale called the pH scale which ranges from 0 to 12. A pH value of less than 7 indicates an acid. The lower the number is, the stronger the acid. The higher the number is, the stronger the base
A certain compound can be an indicator that change color when acid comes in contact with them. In this experiment, red cabbage juice is used as an indicator to detect the PH level of acid and base. We can detect PH Level by observing the color of the substances after the indicator is added. In our experiment, we conducted an experiment with a different substance such as:
- Lime juice
- Lime Soda
- Baking Soda
A solution forms when one substance is dissolved by another. The substance that dissolves is called the solute. The substance that dissolves it is called the solvent. In the case, Lime juice, Vinegar, Lime Soda, Water, Toothpaste, Baking Soda, Bleach are solute. The cabbage represents the solvent. The solute is present in a lesser amount than the solvent. In another work, the cabbage is the indicator. After adding the indicator to the substance, we can see the obvious changes of the properties in each cups.
