QUESTIONS WITH COMPLETE VERIFIED ANSWERS


acid
- a compound whose formula begins with H but also contains a nonmetal or polyatomic
group
- HCl, H2S, H2SO, HNO3, & HC2H3O2
- the H of an acid can be lost (to another material) as a H+ ion (proton) in a chemical
reaction, so acids are called H+ ion (proton) donors
base
- a compound whose formula ends with OH but also contains metal
- NaOH, KOH, & Ca(OH)2, not C2H5OH (ethel alcohol)
- the OH= ion of a base can react with a H+ ion in a chemical reaction so bases are
called H+ ion (proton) acceptors
salt
- a compound whose formula contains a metal combined with a nonmetal or polyatomic
group
- NaCl, Al(NO3)3, & CaSO4
- salts are formed by the neutralization reaction of an acid with a base
acid properties

- turns litmus paper from purple to red
- produce a solution with a pH < 7
