1. 160,000
2. 160,00
You just have to multiply the volume and the buffer.
Answer:
Conditioning two or three times will insure that the concentration of titrant is not changed by a stray drop of water.
Explanation:
"Check the tip of the buret for an air bubble. To remove an air bubble, whack the side of the buret tip while solution is flowing".
The reaction equation:
N₂O₅ + H₂O → 2HNO₃
Moles N₂O₅ = 0.65 / (14 x 2 + 16 x 5)
Moles N₂O₅ = 6.02 x 10⁻³
Molar ratio N₂O₅ : HNO₃ = 1 : 2
Moles HNO₃ = 2 x 6.02 x 10⁻³
Moles HNO₃ = 0.012 mole
Answer:Acids taste sour, react with metals, react with carbonates, and turn blue litmus paper red. Bases taste bitter, feel slippery, do not react with carbonates and turn red litmus paper blue.
Explanation:
- Sour taste (though you should never use this characteristic to identify an acid in the lab)
- Reacts with a metal to form hydrogen gas.
- Increases the H+ concentration in water.
