I 4. C E Determine the pH of a 0.095 mol/L HIO4 solution if the K₂ = 1.29 x 10-² + H₂O (l) HIO4 (aq) H30+ (aq) 10+ (aq) +

How can I find the pH of a weak acid?

Please help me asap with the following question, I have a hard time getting it

Please do it neat and clean correctly please asap

Question 16 of 21 Which one of the following represents the molecular equation for the reaction of HNO3 with CSOH? A) CSOH (aq) + HNO3 (aq) → H₂O (1) + CSNO, (aq) B) Cst (aq) + NO3(aq) → CSNO, (s) C) H+ (aq) + OH- (aq) → H₂O (1) D) CSOH (aq) + HNO3 (aq) → H₂O (aq) + CSNO, (s)

Identifying the major species in weak acid or weak base... The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. acids: 1 mol of NaOH is added to 1.0 L of a 0.7M HCN bases: O solution. other: O 0.3 mol of NaOH is added to acids: 1.0 L of a solution that is bases: O 0.8M in both HCN and NaCN. O other:
