difference between caustic and baking soda

Both caustic soda and baking soda are basic or alkaline inorganic compounds, and their aqueous solutions contain pH level above 7.0. Despite these similarities, there are some important differences between them.

The word ‘soda’ usually refers to the image of a bubbling sweet drink. In soda drinks, carbon dioxide is added to the water mixture and sealed under pressure. Carbon dioxide reacts with water to form carbonic acidwhich then dissociates into carbonate ions (CO )3-2) and bicarbonate ion (HCO.)3,,

Baking soda also forms bicarbonate ions, whereas caustic soda produces hydroxyl ions. As the name suggests, caustic soda is corrosive and is capable of dissolving or decomposing substances such as organic tissue.

Is Baking Soda the Same as Caustic?c leave?

Although baking soda and caustic soda are both alkaline substances that have a pH level above neutral, they are chemically different from each other.

Sodium bicarbonate – better known as baking soda – has the chemical formula NaHCO₃. Meanwhile, caustic soda is also called sodium hydroxide And its chemical formula is NaOH. Importantly, baking soda is non-toxic while caustic soda is toxic.

What is Caustic Soda?

Caustic soda is the common name of sodium hydroxide, Make it a strong . is classified as Base Because its molecules completely dissociate into ions and cations when dissolved in water. Compared to baking soda, it is highly corrosive and toxic. reagent of caustic soda

Sodium hydroxide is commonly used as an ingredient in detergents, drain cleaners and oven cleaners. It is also used in the manufacture of paper to make fibrous pulp from wood cellulose. It can dissolve organic matter and living tissue, causing serious injury.

Sodium hydroxide is also highly hygroscopic, meaning that it readily absorbs moisture in the air.

What is Baking Soda?

Baking soda, or sodium bicarbonate, is commonly used to bake breads, cakes, and pastries. This helps the dough rise by releasing carbon dioxide, which creates bubbles in the mixture. As bubbles form, the dough expands and blanks are left behind when the dough is baked.

The bakery sprinkles flour on the dough before it is kneaded.

Baking soda is non-toxic and can be easily broken down into simpler chemical components. At temperatures starting from 80 °C, it seems to disintegrate In three simple compounds – sodium carbonate, water and carbon dioxide. The decomposition accelerates as the temperature increases.

The release of carbon dioxide during this decomposition process means that sodium bicarbonate can be used to extinguish the fire. In fact, it is the main active ingredient in pressurized firefighting tanks.

Is Baking Soda Caustic?

Baking soda, no matter how concentrated, has a relatively low pH and is considered a weak base. As a weak base, baking soda is not able to remove hydrogen ions (protons) from other compounds.

When dissolved in water, it dissolves into sodium and bicarbonate ions. Unlike hydroxyl ions, bicarbonate ions do not readily accept protons, which makes baking soda non-caustic.

Are Caustic Soda and Baking Soda the Same Thing?

Although both caustic soda and baking soda are alkaline substances and have similar names, they are not the same thing. For starters, they have different chemical formulas and properties. One is poisonous while the other is non-toxic and can be used as a food ingredient.

Due to sodium’s high reactivity, a lot of energy (such as an electric current) is required to decompose or chemically change caustic soda. However, baking soda only needs a relatively low temperature to decompose. Although the latter also contains sodium, one of the products of its decomposition is water. This makes it easier for sodium to partner with free hydroxyl ions in water.

Baking soda usually occurs as a white powder at room temperature. In contrast, caustic soda is flaky white and becomes ‘wet’ at room temperature because it readily absorbs moisture. Caustic soda flakes in a black ceramic bowl

Its hygroscopic properties make it less than ideal for use in standard solution Because the pH level can be easily skewed by the presence of moisture in the air. Caustic soda is also too reactive to be stable enough as a standard solution.

Can I Use Baking Soda Instead of Caustic Soda?

Whether or not you can use baking soda in place of caustic soda depends on the context or purpose. For example, you can use baking soda to neutralize acid, you can also use it in titration experiment,

However, if you want to produce stronger detergents and cleaning agents, you cannot use baking soda in place of caustic soda because it does not have the same protonation effect.

In most cases, baking soda and caustic soda are not interchangeable. Their chemical and physical properties are so different that one cannot be an effective substitute for the other.
