Answer: The values for Ka and Kb for the species in solution must be known before a prediction can be made
Explanation:
1. If Ka is greater than Kb, the salt solution is acidic
2. If Ka is lesser than Kb, the salt solution is basic
3. If Ka is equal to Kb, the salt solution is acidic
Answer:
1800 pascal
Explanation:
p1v1 = p2v2
p1v1/v2 = p2
90 * 2000 / 100 = p2 = 1800 pascal
2Nal+CaCl2 should be right
Answer:
A base accepts hydrogen ions.
