What's Your pH-losophy?
This scientist defined an acid as a substance that produces H+ ions in water, and a base as one that produces OH- ions.
What is the Arrhenius definition?
In the reaction HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l), these two ions are spectators.
What are Na+ and Cl-?
Calculate the pH of a solution made by dissolving 7.30 g of HCl in 0.500 L of water.
What is pH = 0.398?
HCl fully dissociates in water. HCH3COO only partially dissociates. This key difference makes HCl this type of acid.
What is a strong acid?
For HCl(aq) + H2O(l) → H3O+ + Cl-, adding more HCl shifts the equilibrium in this direction.
What is to the right (toward products)?
In the reaction HCl + H2O → H3O+ + Cl-, identify the conjugate base.
What is Cl-?
Write the net ionic equation for the neutralization of any strong acid with any strong base.
What is H+(aq) + OH-(aq) → H2O(l)?
If the pOH of a solution is 11.42, what is the pH?
What is pH = 2.58?
The double arrow (⇌) in HCH3COO + H2O ⇌ CH3COO- + H3O+ indicates this about the reaction.
What is that it is a reversible equilibrium?
For the same HCl reaction (HCl(aq) + H2O(l) → H3O+ + Cl-), removing H3O+ causes this shift.
What is to the right (toward products)?
Give the acid or base name for HCl dissolved in water.
What is hydrochloric acid?
In AgNO3(aq) + NaCl(aq) → AgCl(?) + NaNO3(aq), AgCl forms this type of product indicated by its state symbol.
What is a precipitate (solid)?
A solution has a pH of 2.58. Which indicator from this list best confirms it — Methyl Orange, Phenolphthalein, or Alizarin Yellow?
What is Methyl Orange?
NH3 is a weak base. In its reaction with water, it produces these two ions.
What are NH4+ + & OH-?
Adding a catalyst to HCl(aq) + H2O(l) → H3O+ + Cl- causes this shift.
What is no change in equilibrium position?
In the reaction HCH3COO + H2O ⇌ CH3COO- + H3O+, H2O acts as this.
What is a base?
For the reaction KOH + CH3COOH → KCH3COO + H2O, this is the balanced coefficient for KOH.
What is 1? (1KOH + 1CH3COOH → 1KCH3COO + 1H2O)
Calculate the pOH of a solution made by dissolving 5.60 g of KOH in 0.700 L of water.
What is pOH = 0.846?
H3PO4 is a weak polyprotic acid. In its first dissociation step with water, it loses one H+ to form this ion.
What is H2PO4-?
For the reaction NH3 + H2O ⇌ NH4+ + OH-, adding more NH4+ to the solution shifts the equilibrium in this direction.
What is to the left (toward reactants)?
KOH is classified as this type of Arrhenius base, and its systematic name includes this word describing the metal.
What is potassium hydroxide?
In BaBr2 + H2SO4 → BaSO4 + HBr, balance the equation. State the coefficient in front of HBr.
What is 2? (1BaBr2 + 1H2SO4 → 1BaSO4 + 2HBr)
A NH3 solution has a pOH of 4.71. State the pH and the [H+] concentration.
What is pH = 9.29 & [H+] = 5.13 x 10-10 M?
HCl is written with a single arrow (→) in its reaction with water, while HCH3COO uses a double arrow (⇌). What does this difference in notation tell you about how each acid behaves in solution?
What is that HCl fully dissociates (strong acid) while HCH3COO only partially dissociates (weak acid)?
For the reaction NH3 + H2O ⇌ NH4+ + OH-, removing OH- from the solution shifts the equilibrium in this direction, and this is what happens to the concentration of NH4⁺ as a result.
What is a shift to the right, causing NH4+ concentration to increase?
