Daily Chemistry: Acids, Bases and common elements
What are Acids?
Acids are substances that have a pH level below 7. Acids can be either strong or weak, depending on their concentration. Strong acids are typically found in concentrated forms, such as hydrochloric acid (HCl), while weak acids are typically found in dilute forms, such as lemon juice.
Examples of Acids:
Hydrochloric acid (HCl)
Sulfuric acid (H2SO4)
Nitric acid (HNO3)
Acetic acid (CH3COOH)
Lemon juice
What are Bases?
Bases are substances that have a pH level above 7. Bases can also be strong or weak, depending on their concentration. Strong bases are typically found in concentrated forms, such as sodium hydroxide (NaOH), while weak bases are typically found in dilute forms, such as baking soda (NaHCO3).
Examples of Bases:
Sodium hydroxide (NaOH)
Potassium hydroxide (KOH)
Ammonia (NH3)
Sodium bicarbonate (NaHCO3)
Calcium hydroxide (Ca(OH)2)
Common Elements:
The following are some of the most common elements in the universe:
Hydrogen
Oxygen
Carbon
Nitrogen
Sodium
Potassium
Calcium
Aluminum
**The periodic table is a chart that organizes the elements by their atomic number, which is the number of protons in the nucleus of an atom. The periodic table is a valuable tool for understanding the properties of elements and for predicting their behavior
