A solution with a pH of 7 has equal concentrations of protons (H+) and hydroxides (OH-). The concentration will be 1 x 10-7 M for both. A pH at this number is referred to as neutral (not acidic or basic due to equal concentrations of protons and hydroxides). Water has a pH around 7, making water a neutral compound in most cases.
A solution of pH 7 is perfectly neutral. It has equal concentrations of hydronium and hydroxide (which exist in equilibrium with water); pure water in a selaed airless container is ~pH 7, although air and temperature can affect it through the formation of carbonaic acid and because of thermodynamics. Solutions can be formed to adjust this using many different compound combinations to perfect the pH of a solution to 7.
In practise, many are close enough that there may as well not be a difference (a common concept when dealing with pH and solutions). They include pure water itself, sugar solutions, those of many different salts and some organic compounds.
A neutral aquous solution has a pH value of 7.0 at 25 oC.
Although theoretically it could be a number of possibilities, with a pH level of 7, the solution is most likely to be distilled water.

A neutral solution would have a pH of 7.
Neutral solution: pH =7Acidic solution: pH7.
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
pH = 0-7 acidic solution pH = 7 neutral solution pH = 7-14 basic solution
A pH 2 solution is 100,000 times more acidic than a pH 7 solution. pH 2 is acidic whereas pH 7 is neutral
A neutral solution would have a pH of 7.
Neutral solution: pH =7Acidic solution: pH7.
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
pH = 0-7 acidic solution pH = 7 neutral solution pH = 7-14 basic solution
The pH of a neutral solution is 7 and the concentration of H+ or H3O+ in the solution would be 1.0 X 10-7.
Basic solutions have a pH greater than 7
The water solution of sodium chloride is neutral.
A pH 2 solution is 100,000 times more acidic than a pH 7 solution. pH 2 is acidic whereas pH 7 is neutral
neutral
Solutions with a pH over 7 are basic, and the higher the number, the stronger a base they are. A solution with a pH of 8 is a base.
NaOH is a base so it will produce a pH above 7.
Calcium chloride does not affect pH so a solution of it would have a pH of 7
