Analyze how friction can be positive and negative aspect in our everyday lives

100 ml

Explanation:

The neutralization reaction is:

NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)

Since 1 mol NaOH reacts with 1 mol HCl, at the equivalence point of the titration, the number of moles of NaOH is equal to the number of moles of HCl. We calculate the moles as the product of molarity (M) and volume (V):

moles NaOH = moles HCl

M(NaOH) x V(NaOH) = M(HCl) x V(HCl)

Thus, we calculate the volume of NaOH needed to completely neutralice HCl:

V(NaOH) = (M(HCl) x V(HCl)) /M(NaOH)

               = (0.02 M x 50 ml)/ (0.01 M)

               = 100 ml

Therefore, 100 ml of 0.01 M NaOH are required to neutralize 50 ml of 0.02 M HCl.
