Given:
0.607 mol of the weak acid
0.609 naa
2.00 liters of solution
The solution for finding the ph of a buffer:
[HA] = 0.607 / 2.00 = 0.3035 M
[A-]= 0.609/ 2.00 = 0.3045 M
pKa = 6.25
pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
Answer:
i need a picture of ur question
Explanation:
I have never heard of the term native elements before but that must be it since carbonates contain CO₃, halides contain a halogen, and sulfates and sulfide contain either SO₄ or SO₃. Gold, silver, and copper can all become carbonates, sulfates or sulfides, and halides. However, by them selves they don't.
Answer:
An alcohol thermometer can easily measure the boiling point of a colorless liquid that boils at 100 °C.
A mercury thermometer can easily measure the boiling point of a colorless liquid that boils at 82 °C.
A mercury thermometer can easily measure the freezing point of a colorless liquid that freezes at −50 °C.
or An alcohol thermometer can easily measure the freezing point of a colorless liquid that freezes at −110 °C.
