The correct answer is Sodium hydroxide.

Key Points 

  • Sodium hydroxide (NaOH) dissociates completely in water to give Na+ and OH−
  • Sodium hydroxide is considered a strong base as all the available [OH] in NaOH is present in the solution as [OH−] and available to accept protons.
  • Sodium hydroxide is the strongest base because it totally dissociates to form sodium ions and hydroxide ions.
  • These hydroxide ions are treated with hydrogen ions further from the acid and totally ionize the hydrogen ions.
  • Producers may utilize sodium hydroxide to manufacture soaps, rayon, paper, products that explode, dyes, and petroleum products.
  • Other works that may utilize sodium hydroxide comprise preparing cotton fabric, metal cleaning and preparing, oxide coating, electroplating, and electrolytic extraction.
  • It has the pH value of about 14.

Additional Information

  • The blood has a normal pH range of 7.35 to 7.45.
  • Milk of Magnesia is basic in nature. The pH value of the Milk of Magnesia is 10.5.
