Difference Between Sodium and Potassium

Main difference

The main difference between sodium and potassium is that sodium is a white chemical element that combines with other chemicals, while potassium usually appears in compounds.

Sodium vs Potassium

Sodium is an important element for human metabolism, while potassium controls blood pressure and relaxes the walls of blood vessels. Cornflakes have 266 mg of sodium. Potassium in cornflakes is 33 mg. French bread can contain 82 mg of sodium. Potassium in French bread is 416 mg. Fast food has 444 mg of sodium. Fast food has 1176 mg of potassium. Milk contains 336 mg of sodium. The potassium found in milk is 107 mg.

Peanuts and unsalted butter are 208% sodium. Peanuts and unsalted butter have 5% potassium. The first chemical abbreviation for sodium came in 1814. Firstly, Sir Humphrey Davy in 1807 introduced potassium to the world.

Sodium has atomic number 11, atomic weight 22.99, boiling point 892 °C, and special gravity 0.971. Potassium has atomic number 19, atomic weight 39.102, boiling point 774 °C, and special gravity 0.862.

What is sodium?

Sodium is also known as “salt.” The word sodium derived from the Arabic word ‘soda’ means ‘headache’. Most Romans called it “salary”, and this word is derived from “solarium”. In Latin, sodium is known as “sodium.” The German chemist in 1809 Ludwig Wilhelm Gilbert gives it the name of nitronium.

Sodium color shows effective orange light. It is a more malleable metallic element that reacts with water. It is the sixth most sufficient element of the surface. You can widely use it as chemical reagent and raw material. He is a good supporter of metallurgy, heat transformation, and sodium vapor lamps, etc.

You can find it in baking soda, caustic soda, sodium nitrate, and sodium chloride. Soda ash is the fourth basic element used to make cleaners. Sodium hypochlorite acts as a household bleach, helping to whiten paper pulp and textiles and to chlorinate water.

Sodium carbonate is also used in medicines. Sulfate helps in kraft procedures to create cardboard. Thiosulfate comes to take pictures. Examples of sodium are rock salt (halite) NaCl, Chilean salt NaNa3, sun flower, Himalayan pink salt, kosher salt, monosodium glutamate, etc.

What is potassium?

Potassium is an important element for the human body. It plays an important role in health. In the 1880s and 1890s, the world investigated potassium. Potassium controls blood pressure and relaxes the walls of blood vessels. A human body uses 4.7 billion grams of potassium in a day.

Man mainly use 3000 mg/day and women 2300 mg/day. But potassium can be dangerous for older adults. We can get potassium from potatoes, beans, peas, tomatoes and oranges etc. This soft, silvery element helps make glass, soap, and fertilizer.

You can get it from the electrolysis of its common hydroxide and change it into various kinds of salts, especially for fertilizers. Especially, we can find it in seawater, carnallite, kainite and sylvite. Most of the time it doesn’t come for free and is sometimes used as a metal due to its reaction.

Potassium is the basic element of life and is found in almost all soils. Potassium ions and sodium ions act on cell membranes in the transmission and transport of electrochemical impulses. Hydroxide supports for the manufacture of liquid soaps and detergents. Iodide makes its way into table salt to ward off iodine shortages.

Key differences

  1. Sodium is very hard, while potassium is a soft element.
  2. Sodium has an atomic weight of 22.98.0 C; on the other hand, potassium has an atomic weight of 28.98.0C.
  3. Sodium is mainly used by humans and animals; on the contrary, animals and plants use potassium.
  4. The boiling point of sodium is 882.8 °C; on the other hand, the boiling point of potassium is 759 0C.
  5. The sodium found in a banana is 422 mg, while the potassium found in a banana is 1 mg.
  6. In orange, the sodium is 232 mg; on the other hand, potassium is 1 mg.
  7. The atomic size of sodium atoms is smaller; on the other hand, the atomic size of potassium atoms is larger.

Final Thought

Sodium and potassium are vital elements for the existence of animals and plants. We can judge its difference by size and weight.
