<span>Question: Organic chemistry is the study of compounds containing?

Answer: (A) Carbon Organic chemistry is the study of compounds that contain the element carbon, or the study of carbon-containing molecules and the compounds they form. An entire branch of chemistry (carbon chemistry) is dedicated to this subject. Which means carbon is quite important, after all it is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and Organic compounds together scientists can learn more about life, the human body, and how it works!</span>

What is the solubility of KI at 10C?

Bingel [31]

31.2g per 100g of water.

Explanation:

The required result about the solubility of KI at 10C is measured to be 31.2g per 100g of water.
Every solution contains a volume and that gets changed radically when the dissolution comes into existence. The result can be seen by inspecting the solubility in mol⋅L−1.
If we look closely to understand the solubility of KI, either at 10C or at any other temperature, you can ease it by a trick. The solubility of potassium bromide is approx twice its value.

It takes 24.56 mL of a sodium hydroxide solution to precisely neutralize 2.023 g of potassium hydrogen phthalate (F.W. = 204.22g

Alinara [238K]

Answer:

0.4033 M is the concentration of the sodium hydroxide solution.

Explanation:

Mass of potassium hydrogen phthalate = 2.023 g

Molar mass of potassium hydrogen phthalate = 204.22 g/mol

Moles of potassium hydrogen phthalate :

= $\frac{2.023 g}{204.22 g/mol}=0.009906 mol$

$C_8H_5KO_4+NaOH\rightarrow C_8H_4KO_4Na+H_2O$

According to reaction, 1 mole of potassium hydrogen phthalate reacts with 1mole of NaOH. Then 0.009906 moles of potassium hydrogen phthalate will recat with:

$\frac{1}{1}\times 0.009906 mol=0.009906 mol$ of NaOH

Moles of NaOH = 0.009906 mol

Volume of NaOH solution = 24.56 mL = 0.02456 L

$Molarity=\frac{Moles}{Volume (L)}$

$[NaOH]=\frac{0.009906 mol}{0.02456 L}=0.4033 M$

0.4033 M is the concentration of the sodium hydroxide solution.
