pH is a measure of acidity/basicity. pH range is 0-14. Caustic soda is used for cleaning and baking soda is used in cooking.
pH measures the concentration of hydrogen ions in a solution. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic.
The pH range is from 0 to 14, with 0 being the most acidic and 14 being the most basic.
Caustic soda, also known as sodium hydroxide, is a strong base used for cleaning and in...
Molarity and molality are both measures of concentration in a solution.
Molarity is the number of moles of solute per liter of solution.
Molality is the number of moles of solute per kilogram of solvent.
Molarity is temperature dependent, while molality is not.
Molality is often used in calculations involving colligative properties.
Example: A solution containing 0.5 moles of NaCl in 1 liter of water has a molarity of 0.5 M
