6.1: Identifying Acids and Bases

Question 1

taste of acids and bases

Answer 1

acids are sour, bases are bitter

Question 2

acid

Answer 2

a compound that produces hydrogen ions (H+) when dissolved in water

Question 3

conductivity of acids

Answer 3

aqueous solutions of acids are conductive because ionization (forms ions as it dissolves in the water) is triggered. The ions make it conductive

Question 4

name a binary acid

Answer 4

classical: hydro-nonmetal-ic acid
IUPAC: aqueous [ionic -ide name]

Question 5

application of acids

Answer 5

in art: etching glass

Question 6

name oxoacids

Answer 6

[anion name] acid
BUT
in the anion name, replace -ate with -ic and replace -ite with -ous

root exceptions: sulphuric and phosphoric (not sulphic and phosphic)

Question 7

bases

Answer 7

release hydroxide ions (OH-) when dissolved in water - process of dissociation

Question 8

characteristics of bases

Answer 8

slippery feeling

conductive

Question 9

name bases

Answer 9

just like ternary ionic compounds (metal + OH)

Question 10

sodium hydroxide

Answer 10

one of the most important chemicals in industry
mass produced by the chlor-alkali process (name: because it is produced simultaneously with chlorine gas, also very important). process involves the electrolysis of aqueous sodium chloride

used for paper production, aluminium production, soaps and detergents, and the manufacturing of chemicals
