- Acids are substances that form H^+ ions when dissolved in water.

- Bases are substances that form OH^- ions when dissolved in water.

- Substances with a Low pH ( < 7) have more H^+ ions are classified as Acids.

- Substances with a Higher pH ( > 7) have more OH^- ions and are classified as Bases.

The pH of a solution/substance is a measure of the molar concentration of hydrogen ions in solution/substance and as such, is a measure of the Acidity or Basicity of the solution/substance.

The letters pH stands for " Power of Hydrogen." and the:

Numerical Value: is defined as the Negative Base 10 Logarithm of the Molar Concentration of Hydrogen Ions.

pH = log10[ H^+]

Hope this Helps!!!!

Answer:

chemonoia

Explanation:

Many people have a strong fear of “chemicals” that belies the evidence. It's called chemonoia – and it may be damaging their health. If you were paranoid, you might think there really was something in the water that's damaged our sense of reason.

Complete the equation to show how hydrofluoric acid, HF, acts as a Brønsted-Lowry acid in water. Balanced equation:

shepuryov [24]

Answer : The balanced equation is,

$HF+H_2O\rightleftharpoons H_3O^++F^-$

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

The balanced chemical reaction will be,

$HF+H_2O\rightleftharpoons H_3O^++F^-$

In this reaction, hydrofluoric acid is act as a Bronsted Lowry-acid because it donate one hydrogen ion to $H_2O$ and $H_3O^+$ is act as a Bronsted Lowry-base because it accept one hydrogen ion from $HF$ .
