Acids ACIDS The word acids comes from one of its characteristic properties, its taste. ACIDS = “acidus” (latin word) meaning sour.

Acids ¡ ¡ An acid is a substance that releases H+ ions in an aqueous solution An aqueous solution is a solution that contains water. HCl H+ + Cl-

Bases are substances that are very slippery to touch and have a strong bitter taste. BASES

Bases ¡ A base is a substance that releases OH- ions in an aqueous solution Na. OH Na+ + OH-

Salts SALTS Salts are formed by the bonding of a metal with a non-metal. They are often used to change the physical properties of various solutions by lowering the freezing points or raising the boiling points

(USED TO DETECT ACIDS OR BASES) Litmus paper is a type of indicator (thin strip of paper that is dipped into a solution) 2 Types: Blue Litmus Paper Red Litmus Paper ACIDS – Turn blue litmus paper red BASES – Turn red litmus paper blue BB
![Indicators SALTS – most salts are neutral Indicators SALTS – most salts are neutral](http://slidetodoc.com/presentation_image/3c8efb6ae79397de30800bca925040e9/image-9.jpg)
Indicators SALTS – most salts are neutral

Properties of Acids, Bases and Salts ACID Electrolyte Magnesium YES Reaction to produce hydrogen H+ ions BASE YES No Reaction Taste/ Touch Litmus Paper Sour Turns red Bitter/ Slippery OH- ions SALT Other ions YES No Reaction Salty Turns Blue No change in colour Electrolytes – solutions that conduct electricity
![“Making a solution chemically neutral” Chemically neutral – means does not contain an acid “Making a solution chemically neutral” Chemically neutral – means does not contain an acid](http://slidetodoc.com/presentation_image/3c8efb6ae79397de30800bca925040e9/image-12.jpg)
“Making a solution chemically neutral” Chemically neutral – means does not contain an acid or base Neutralize it with an acid Acids and bases neutralize each other forming a salt and water Ex. Acid + Base = Salt + water
