Q:

What are neutral substances?

A:

Quick Answer

Neutral substances are chemicals that have no properties of either acids or bases, have equal parts hydrogen and hydronium ions and don't change the color of litmus paper or other acid-base indicators. Neutral substances include water, glucose solutions and salt solutions. These chemicals have a pH of 7.0 on a scale of 14. In terms of toxicity, neutral substances are generally harmless to the touch.

Full Answer

Pure water has no ions in it whatsoever and serves as the main solvent in which acids and bases are dissolved. A sugar solution is made of molecules of carbon, hydrogen and oxygen atoms bound together in a crystalline pattern. A salt solution in pure water has dissolved sodium and chlorine ions.

Acids and bases have higher concentrations of either hydrogen ions with a plus charge or hydronium ions with a plus charge. Hydronium molecules consist of three atoms of hydrogen bound to one atom of oxygen. Acids have more hydrogen ions, and bases have more hydronium ions. Neutral substances have neither ion, or an equal number of both ions, to cancel out any acid or base properties.

While a neutral solution has a pH of 7.0, strong acids have pH numbers closer to zero and strong bases have pH measurements close to 14.

  • Q:

    What is a neutral pH level?

    A:

    A neutral pH level is a value of seven on the pH scale. This number lies at the center of the scale and is the value that is associated with pure water. A pH level below or above seven indicates that the liquid is either an acid or a base.

  • Q:

    How does soil affect the pH of water?

    A:

    Depending on the chemicals in the soil, the pH of water passing through it increases, decreases or remain the same. In areas where water passes through soil containing limestone, dissolving the calcium carbonate in water creates a buffer solution, tying up the hydrogen or hydroxyl ions in the water so the pH becomes less likely to change.

    Which two functional groups are always found in amino acids?

    A:

    The two functional groups always found in amino acids are carboxyl and amino groups. Both groups are acidic. A peptide bond occurs when the carboxyl group of one amino acid joins the amino end of another.

  • Q:

    Which acids dissolve limestone?

    A:

    Carbonic acid, hydrochloric acid and acetic acid are some acids that react with limestone, causing it to dissolve. Each of these acids reacts with limestone in different ways. Limestone is made up mainly of calcite that is the chemical compound calcium carbonate.
