Calculate the concentration of h3o+ in a solution that contains 5.5 × 10-5 m oh- at 25°c. identify the solution as acidic, basic, or neutral.
a. 1.8 × 10-10 m, acidic
b. 9.2 × 10-1 m, basic
c. 5.5 × 10-10 m, neutral
d. 9.2 × 10-1 m, acidic
e. 1.8 × 10-10 m, basic

The correct answer is option (e).

Explanation:

Concentration of hydroxide ions

The pOH of the solution is defined as negative logarithm of hydroxide ions of in an aqueous solution.

Higher the value of pOH more will be the acidic solution.Lower the value of pOH more will be the basic solution.At value  equal to 7 the solution is said to be neutral.

pH +pOH = 14

pH = 14-pOH

pH=14 - 4.259 = 9.741

The pH of the solution is defined as negative logarithm of hydronium ions of in an aqueous solution.

Higher the value of pH more will be the basic solution.Lower the value of pH more will be the acidic solution.At value equal to 7 the solution is said to be neutral.

The solution is basic as pH of the solution is 9.741.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
