acid strength is mainly depend on the active hydrogen ( the "H" atoms attached with highly electronegative atoms such as F,N,O etc or with some groups like C=O gp). basic st…rength depends on how easily -OH is available i.e. mainly depends on the electronegativity of that atom from which -OH gp is attached.
A pH OF 7 It should be pH 7 provided they are the same molare amounts of NaOH and HCl. If they are thne same weights, the pH will not be 7
Water and a salt.
On a scale of 1-14 measuring the concentrations of Ph and POh.
Generally, an acidic salt and water will form, but not always. I must assume you mean equimolar and not equal amounts, for it is very difficult to tell if you have not stated… specific acids/bases.

When you take equal amounts of such couple they will neutralise each other precisely and completely (pH = 7.0)
A salt and usually water.
pKa is a good measure of the strength of an acid; the corresponding version for bases is usually pKb, though the pKa of their conjugate acid could also be used. You can also …just use the straight dissociation constant (Ka or Kb) itself, but taking the negative log of it can be useful, since it compares more directly to the pH of a solution of the material.
It depends on the pH level. Water is consider neutral at a pH of 7. Anything stronger (greater than 7) is considered basic and anything weaker is considered acidic.
The strength of acids and bases is most often indicated by the concentration of hydrogen ions in the solution. This is called the pH.
The amount of H+ ions liberated when an acid is dissolved in water is the strength of the acid (OH- ions in the case of a base). In addition, in the case of acids, the pH wil…l be between 1-7 and in the case of bases, the pH will be between 8 to 14.
The most obvious effect is the emission of carbon dioxide.
