Answer 2

soluble ion OH⁻ comps, use solubility table

Question 3

exceptions for strong bases

Answer 3

If they have Ca, Sr, Ba in them

Question 4

times when smth is always soluble

Answer 4

if it has NO₃⁻, C₂H₃O₂⁻, NH₄⁺, or alkali metal ions in it

Question 5

write that freaking rxn for weak bases

Answer 5

NH₃ (aq) + H₂O (l) ⇌ NH₄⁺ (aq) + OH⁻ (aq)

Question 6

write the neutralization rxn template

Answer 6

H⁺ acid + OH⁻ base ⇌ H₂O (l) + ion comp salt

Question 7

write out the precipitation rxn template

Answer 7

ion comp (aq) + ion comp (aq) → ion comp (aq) + ion comp (s)

Question 8

recipe for hydronium

Answer 8

H⁺(aq) + H₂O(l) → H₃O⁺(aq)

Question 9

template for gas evolution rxn (just used to ID them on test so you can apply the 3 subtemplates)

Answer 9

acid (aq) + ion comp (aq) or (s) → cov comp (g) + ion comp (aq) or (s)
