<span>The pH of ethanol is 7.33, while the pH of 2-naphthol is 8.5. Hence as both substances have a pH greater than 7, they are classified as basic substances rather than acidic. However, as ethanol has a lower pH than 2-naphthol it is more acidic than 2-naphthol, and this is due to ethanol dissociating in solution to form a lower number of hydrogen ions than 2-naphthol.</span>
Answer: the answer is 26, I have the same course
Explanation:
Answer:
f. Sn^4+
c. second
e. Al^3+
d. third
Explanation:
This question comes from a quantitative analysis showing the flowchart of a common scheme for identifying cations.
Now, from the separation scheme, Let's assume that Sn⁴⁺ & Al³⁺ were given; Then, Yes, the separation will work.
However, there will be occurrence of precipitation after the 1st step1.
So, the <u>Sn⁴⁺</u> cation will precipitate after the <u>second </u>step. Then the <u>Al³⁺</u> cation will precipitate after the <u>third</u> step.
Explanation:
Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
