Answer #1

Identify the ions that exist in each aqueous solution, and specify the concentration of each ion

0.25M (NH4)2SO4

0.123M Na2CO3

0.056M HNO3

  1. (NH4)2SO4àà 2NH4+ + SO42-

Concentration of (NH4)2SO4 is given as 0.25M,

Therefore after dissociation;

from above equation we can calculate concentration of individual ion as follows,

  1. × 0.25= 0.5M
  2. × 0.25 = 0.25M
  1. Similarly we can calculate for other two compound ,

Na2CO3 àà 2Na+ + CO32-

  1. × 0.123 = 0.246 M
  2. CO32-] = 0.123M
  1. HNO3 àà H+ + NO3-
