Difference Between Lye and Acid

Differences and similarities between acids and alkalis

• When speaking of acids and alkalis, one usually means acids and bases according to Brönsted. In addition to these, there are also acids and bases according to Lewis.
• Brönsted acids and alkalis are both corrosive and some can be devastating, but they are fundamentally different.
• A Brönsted acid is defined as a proton donor, i.e. i.e., these particles are capable of H⁺-Ions split off.
• The difference to a Brönsted base is its fundamental property: bases are proton acceptors, i. h., you can H⁺Absorb ions.
• If an acid releases its proton, the resulting particle is basic. Since it previously carried a proton, it can also take it up again and is therefore a base. This is called the corresponding base and one always speaks of corresponding acid-base pairs.

Neutralize the lye

An alkaline solution can be neutralized with an acid - that's logical, are ...

• Acids and bases can be classified according to their strength, i. H. depending on how willing they are to give up a proton or take up. If an acid is very strong, its corresponding base is very weak and vice versa.
• Whether a solution is acidic or basic is indicated by the pH value, which can assume a value between 0 and 14; pH 7 means that the solution is neutral, 0-6 is acidic and 8-14 is basic. The further away the value is from 7, the more acidic or acidic. the solution is basic.

Acids and alkalis in everyday life

• Many cleaning agents are acidic or basic. Acids have the property of dissolving limescale, so limescale cleaners are acids.
• Many soaps are caustic solutions; pH skin-neutral soaps are slightly acidic as the skin's pH value is around 5.
• There is a very strong acid in the human body: the pH value of gastric acid is 1-2 on an empty stomach and 2-4 on a full stomach. This strong acid does not etch through the stomach wall as it is protected by the stomach lining.
