solubility vs. temperature for a variety of salts\nwhich two solutions have similar solubilities at 40°c?\nna2so4 and nacl\nna2haso4 and nacl\nna2haso4 and na2so4\nba(no3)2 and ce2(so4)3·9h2o
Answer
Explanation:
Step1: Locate 40°C on x - axis
Find the 40°C mark on the temperature axis.
Step2: Check solubilities of salts
Read the solubility values of each salt at 40°C from the graph.
- Solubility of NaCl is around 36 g salt/100 g H₂O.
- Solubility of Na₂SO₄ is around 48 g salt/100 g H₂O.
- Solubility of Na₂HAsO₄ is around 48 g salt/100 g H₂O.
- Solubility of Ba(NO₃)₂ is around 24 g salt/100 g H₂O.
- Solubility of Ce₂(SO₄)₃·9H₂O is around 5 g salt/100 g H₂O.
Step3: Compare solubilities
Compare the solubility values to find the pair with similar solubilities. Na₂HAsO₄ and Na₂SO₄ have similar solubilities at 40°C.
Answer:
Na₂HAsO₄ and Na₂SO₄
