Oxalic acid is a diprotic acid with a first dissociation constant Ka1 = 0.0537 and a second dissociation constant Ka2 = 5.42×10-5. Consider all the species in equilibrium with each other in a 0.45 M solution. Note that the first acid dissociation constant is pretty large. This acid is almost a strong acid. Part 1:
What is the concentration of undissociated oxalic acid in the 0.45 M oxalic acid solution?

Part 2:
What is the concentration of hydrogen oxalate?

Part 3:
What is the concentration of oxalate?

Part 4:
What is the concentration of hydronium?

Part 5:
What is the concentration of hydroxide?

Part 6:
What is the pH of the solution?

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
