Answer:
Va = (MbVb)/Ma
Explanation:
Divide both sides by Ma and voila!
Aldehydes may oxidize to form carboxylic acid <span>exception to oxidizing formaldehyde with strong oxidizing agent.
HCHO + 3[O] = CO</span>₂ + H₂O
Answer:
Explanation:
a )
pH = - log[ H⁺]
8.26 = - log[ H⁺]
[ H⁺] = 10⁻⁸°²⁶ mole / l
= 5.49 x 10⁻⁹ moles / l
[ H⁺] [OH⁻] = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / 5.49 x 10⁻⁹
= .182 x 10⁻⁵ moles / l
b )
10.25 = - log[ H⁺]
[ H⁺] = 10⁻¹⁰°²⁵ mole / l
= 5.62 x 10⁻¹¹ moles / l
[ H⁺] [OH⁻] = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / 5.62 x 10⁻¹¹
= .178 x 10⁻³ moles / l
c )
4.65 = - log[ H⁺]
[ H⁺] = 10⁻⁴°⁶⁵ mole / l
= 2.24 x 10⁻⁵ moles / l
[ H⁺] [OH⁻] = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / 2.24 x 10⁻⁵
= .4464 x 10⁻⁹ moles / l
