A neutral solution has a(n) _______ amount of hydroxide ions compared to hydrogen ions.
erastovalidia [21]
The answer is 'equal'. Hydroxide ions are OH- and Hydrogen ions are H+. Have you noticed they're opposite charges? Positive + negative = neutral. That's all there is to it :)

What is the number of millimoles of H+ in 1.653 mmol of oxalic acid dehydrate?Remember that oxalic acid is diprotic.
Anastaziya [24]

Answer: 3.306 mmol

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

Molarity

n= moles of solute  

V_s = volume of solution in ml

C_2O_4H_2.2H_2O\rightarrow C_2O_4^{2-}+2H^++2H_2O

According to stoichiometry:

1 mole of C_2O_4H_2 gives 2 moles of H^+

1.653 mmol of C_2O_4H_2 gives =\frac{2}{1}\times 1.653=3.306mmo of H^+

Thus number of millimoles of H^+ are 3.306
