During the titration of a weak acid and a strong base, you would expect the ph at the endpoint of titration to be
a. less than 7
b. more than 7
c. 7
d. there is not enough information to determine what the ph would be.

The correct answer is Option b.

Explanation: pH is the measure of acidity of basicity of the solution. It is basically known as power of hydrogen ion concentration. pH is the negative logarithmic of hydrogen ion concentration.

Mathematically,

More the hydrogen ion concentration, low is the pH and more acidic is the solution and vice-versa.

pH scale is from 0 to 14.

Acidic solutions vary from pH 0 to 6.9

Basic solutions vary from pH 7.1 to 14.

Neutral solution has a pH of 7.

For the reaction of weak acid (near to 7) and strong base (far from 7), the final pH will be far from 7 or more than 7. Hence, the pH of final solution will be more than 7 and will be basic in nature.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
