6 0
Potential energy (Pe) = m*g*h

m = 4 kg
g = 10 m/s²
h = 3 m

And now:

Pe = 4*10*3

Pe = 120 Joules ou J

During the titration of a weak acid and a strong base, you would expect the ph at the endpoint of titration to be ____.
riadik2000 [5.3K]

Answer is: b. more than 7.

The endpoint is the point at which the indicator changes colour in a colourimetric titration and that is point when titration must stop.

For example, basic salt sodium acetate CH₃COONa is formed from the reaction between weak acid (in this example acetic acid CH₃COOH) and strong base (in this example sodium acetate NaOH).

Balanced chemical reaction of acetic acid and sodium hydroxide:

CH₃COOH(aq) + NaOH(aq) → CH₃COONa(aq) + H₂O(l).

Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base react quantitatively with each other.
