A solution of the primary standard potassium hydrogen phthalate (KHP), KHC8H4O4 , was prepared by dissolving 0.4877 g of KHP in

about 50 mL of water. Titration of the KHP solution with a KOH solution of unknown concentration required 21.66 mL to reach a phenolphthalein end point. What is the concentration of the KOH solution

The following name is wrong. Draw the structure based on it and correct the name: 1,1,1−trimethylheptane
Nana76 [90]

2,2-Dimethyloctane is the correct name.

Eight C atoms make up the longest continuous carbon chain, hence the term "octane" for this molecule.

<h3>Description of the chemical structure</h3>
  • There are 31 bonds in the 2,2-Dimethyloctane molecule overall (s) There are 5 rotatable bonds and 9 non-H bonds (s).
  • Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
  • Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
  • In the 2,2-Dimethyloctane chemical structure, the carbon atoms are implied to be at the corner(s) and hydrogen atoms coupled to carbon atoms are not mentioned; instead, it is assumed that each carbon atom is connected to enough hydrogen atoms to form four bonds.
  • Based on the ball-and-stick model, which shows both the three-dimensional position of the atoms and the bonds tying them together, the 3D chemical structure image of 2,2-Dimethyloctane is created.
  • In order to provide a clearer picture of the atoms and bonds throughout the 2,2-Dimethyloctane chemical structure model, the radius of the spheres is thus smaller than the rod lengths.
<h3>Molecular Formula - C_{10} H_{22}</h3><h3>Chemical Properties</h3>
  • Calculated Log P: 6.434 
  • Molecular Weight: 142.2838
  • Bonds That Rotate: 9  
  • H  Acceptors : 
  • H Donors: 0
<h3>uses </h3>

2,2-Dimethyloctane, a gasoline hydrocarbon byproduct of aerobic biodegradation.

Hydrogen peroxide (H2O2) readily decomposes to form water and oxygen gas: 2H2O2(aq) → 2H2O(l) + O2(g) What concentration of hydr
Anastaziya [24]

Hydrogen peroxide is a powerful oxidizer. When exposed to sunlight it quickly decomposes to form water and oxygen as given by the following equation.

2H2O2(aq) → 2H2O(l) + O2(g)

Hydrogen peroxide is commercially available as a 30% w/w solution, which is the concentration that would facilitate the above reaction. This implies that the concentration would be 30 g of H2O2 in 100 g of the solution.
