Q:

What are some of the properties of acids?

A:

Some of the properties of acids are that they conduct electricity when they are dissolved in water, liberate hydrogen when they react with active metals and, when combined with a base, will produce a salt and a neutralized base. Acids also have a pH which is less than 7 in an aqueous solution, and will change the color of blue litmus paper to red. In an operational sense, acids increase the concentration of H+ ions when they are dissolved in water.

A lower pH of an acid in an aqueous solution indicates a greater degree of acidity, and results in a higher concentration of positive ions within the solution. Acids found in everyday life are usually found in solution. The stronger acids, such as hydrochloric acid (HCl), and some higher concentrations of weak acids tend to be corrosive.

  • Q:

    What are some of the differences between acids and bases?

    A:

    One of the main differences between acids and bases is that acids have a pH that is less than 7 and bases have a pH that is greater than 7. When dissolved in water, acids are substances that will cause the concentration of hydrogen ions (H+) to increase. Bases, when dissolved in water, will instead cause the number of hydroxide ions (OH-) to increase.

  • Q:

    What are neutral substances?

    A:

    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.

    What are the dangers of acids and alkalis?

    A:

    Dr. Sharon Gwaltney-Brant explains on the Veterinary Support Personnel Network that acids typically cause pain upon exposure and produce localized coagulative necrosis of tissue. Alkaline products with a pH level above 11 are capable of causing serious corrosive injury.

    How do you define Bronsted-Lowry acid?

    A:

    Bronsted-Lowry acids are defined as acids that serve as donors for hydrogen protons. Alternately, any base that receives hydrogen protons is called a Bronsted-Lowry base.
