Match the following. 1. A substance that produces hydrogen ions in solution; alternatively, a proton donor
2. A substance that produces hydroxide ions in solution; alternatively, a proton acceptor
a. acid
b. base

1. A substance that produces hydrogen ions in solution; alternatively, a proton donor

Acid

2. A substance that produces hydroxide ions in solution; alternatively, a proton acceptor

Base

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
