(SP -> NO calculator)
What is pOH =2
The concentration of __________ is high in basic solutions.
The concentration of __________ is low in basic solutions
What is OH-
What is H+ or H3O+
Write the dissociation reaction for NH3
What is
NH3 + H2O <--> NH4+ + OH-
pH is the measure of the amount of ___ ion
H3O+ or H+ (hydronium ion or hydrogen ion)
Universal indicator color for thymolphthalein - 8.8 - 9.3 range
Light blue (JUST BLUE -100)
if the pOH = 2, then the H3O+ concentration is this.
(AP -> NO calculator)
What is 1x10-12
HCN + H2O <--> H3O+ + CN−
The acid and conjugate base of this equation is
What is HCN = acid; CN− = conjugate base
HF + H2O <--> F− + H3O+
The base and conjugate base of this equation is
H2O = base F− = conjugate base
Has a pOH of 2 (acid, base or neutral)
Base
