Acidic Solution Definition in Chemistry

In chemistry, any aqueous solution can be classified as belonging to one of three groups: acidic, basic, or neutral solutions. Acidic Solution Definition An acidic solution is any aqueous solution which has a pH 7.0 ([H] 1.0 x 10-7 M). While its never a good idea to taste an unknown solution, acidic solutions are sour, in contrast to alkaline solutions, which are soapy. Examples: Lemon juice, vinegar, 0.1 M HCl, or any concentration of an acid in water are examples of acidic solutions.
