To determine which solvents will catch fire at an ambient temperature of 0 to 5°C, we need to examine the flash points of the solvents provided in the table. The flash point is the lowest temperature at which the solvent can form an ignitable mixture with air.
We are looking for solvents whose flash points fall within the given range, 0 to 5°C.
1. Diethyl ether: Flash point = -45°C
- This flash point is below 0°C. Hence, Diethyl ether can catch fire at an ambient temperature of 0 to 5°C.
2. Dichloromethane: Flash point = 100°C
- This flash point is above 5°C. It will not catch fire at an ambient temperature of 0 to 5°C.
3. Acetone: Flash point = -20°C
- This flash point is below 0°C. Hence, Acetone can catch fire at an ambient temperature of 0 to 5°C.
4. Tetrahydrofuran: Flash point = -14°C
- This flash point is below 0°C. Hence, Tetrahydrofuran can catch fire at an ambient temperature of 0 to 5°C.
5. Hexanes: Flash point = -26°C
- This flash point is below 0°C. Hence, Hexanes can catch fire at an ambient temperature of 0 to 5°C.
6. Ethanol: Flash point = 17°C
- This flash point is above 5°C. It will not catch fire at an ambient temperature of 0 to 5°C.
7. Acetonitrile: Flash point = 2°C
- This flash point is within the range of 0 to 5°C. Hence, Acetonitrile can catch fire at an ambient temperature of 0 to 5°C.
8. Toluene: Flash point = 6°C
- This flash point is just above 5°C. It will not catch fire at an ambient temperature of 0 to 5°C.
After evaluating all the flash points, the solvents that can catch fire at an ambient temperature of 0 to 5°C are:
- Diethyl ether
- Acetone
- Tetrahydrofuran
- Hexanes
- Acetonitrile
However, our final selection specific to this checking process is:
- [tex]$\square$[/tex] Acetonitrile
Thus, the solvent that will catch fire from the given options at an ambient temperature of 0 to 5°C is:
- [tex]$\square$[/tex] Acetonitrile
