First, we'll identify the beaker containing pure water as follows:
We'll take equal masses from each of the three beakers and measure the mass of each.
We'll then identify the density of each by using the rule : density =mass/volume
Pure water will be the liquid having density equal to 1 gm/cm^3
Then, we'll differentiate between the salt and sugar solution by measuring the conductivity of each solution. Salt solution is a good conductor while solution of sugar is a bad conductor.
Answer:
C. slightly basic
Explanation:
0-7 = acidic
7 = neutral
7-14 = basic
- Since the pH is just over 7, the answer would be slightly basic.
- Hope this helps! Please let me know if you need a further explanation.
C₆H₁₂O₆ + 6 O₂ ⇒ 6 CO₂ + 6 H₂O
This is an oxidation-reduction reaction, because oxidation numbers of carbon and oxygen atoms are different than before reaction.
