Hydrogen-Hydrogen
Oxygen=Oxygen
Answer:
Volume of water added = 2.0 L
Explanation:
Initial pH of the solution = 2.7
[H^+] concentration in 2 L solution of sulfuric acid,
Final pH of the solution = 3
Final [H^+] concentration of sulfuric acid,
Now,
Volume added = Final volume - Initial volume
= 4.0 - 2.0 = 2.0 L
a. Hydrogen
Hydrogen has a line at 410 nm.
Mercury has a line at 405 nm.
Sodium and neon have no lines near 412 nm.
