Naming of Acids

Binary Acids (H+ and a nonmetal)

hydro (nonmetal) -ide + ic acid

HCl (aq) = hydrochloric acid

Ternary Acids (H+ and a polyatomic ion)

(polyatomic ion) -ate +ic acid

HNO3 (aq) = nitric acid

(polyatomic ion) -ide +ic acid

HCN (aq) = cyanic acid

(polyatomic ion) -ite +ous acid

HNO2 (aq) = nitrous acid

Formula Writing of Acids

Acids formulas get written like any other. Write the H+1 first, then figure out what the negative ion is based on the name. Cancel out the charges to write the formula. Don’t forget the (aq) after it…it’s only an acid if it’s in water!

Carbonic acid: H+1 and CO3-2 = H2CO3 (aq)

Chlorous acid: H+1 and ClO2-1 = HClO2 (aq)

Hydrobromic acid: H+1 and Br-1 = HBr (aq)

Hydronitric acid:

Properties of Bases

Bases react with fats to form soap and glycerol. This process is called saponification.

Bases have a pH of more than 7.

Dilute solutions of bases taste bitter.

Bases turn phenolphthalein PINK, litmus BLUE and bromthymol blue BLUE.

Bases neutralize acids.

Bases are formed when alkali metals or alkaline earth metals react with water. The words “alkali” and “alkaline” mean “basic”, as opposed to “acidic”.
