The modern periodic law states that properties of elements are periodic functions of their atomic numbers (number of protons). This was established by Henry Moseley. Mendeleev's original table used atomic mass, but the modern table resolves anomalies by ordering by atomic number.
Explanation:
According to Faraday's First Law of Electrolysis, the mass (m) of a substance deposited at an electrode is directly proportional to the total quantity of electricity (Q) passed through the electrolyte. Since Q = Current (I) × Time (t), the mass is directly proportional to both the current and the time.
Explanation:
Sodium carbonate (soda ash) is dissolved in water and crystallized to obtain washing soda. Heating baking soda gives anhydrous sodium carbonate. Brine electrolysis gives NaOH, Cl₂, H₂. Solvay process makes Na₂CO₃.
