Answer:

H2C2O4.2H20 → CO2 + CO + H2O

Explanation:

Oxalic acid crystals are nothing but dehydrated oxalic acid (H2C2O4 . 2H2O).

On heating, the water of crystallization is lost first. Then, the dehydrated oxalic acid decomposes into carbon dioxide(CO2), carbon monoxide(CO) and water(H2O).

Equations involved :

H2C2O4 . 2H2O → H2C2O4 + 2H2O

H2C2O4 → CO2 + HCOOH (FORMIC ACID)

HCOOH → CO + H2O

Overall equation : H2C2O4.2H20 → CO2 + CO + H2O

What is the ph of an aqueous solution with the hydronium ion concentration : [h3o+] = 3 x 10-5 m ?
BaLLatris [955]

The concentration of hydrogen can be shown as:

[H+ ] = 3 * 10-5 M

pH can be determined as:

pH = - log [H+ ]

= - log (3 * 10-5)

= 4.53

Thus the pH of solution is 4.53
