Chemical change cuz you are adding another substance to your water which changes the molecular structure of the water.
Answer:
The structure for the compound elucidated (4-Ethylbenzoic acid) is attached below.
Explanation:
Degree of Unsaturation =
(where n = no of moles)
=
= 9 - 6+1 = 4
⇒ 2 ring. 3 double bonds.
From the 1H NMR data given (peaks labeled A-E)
A. 1.2 (3H, t) ⇒ -CH3
B. 2.6 (2H, q) ⇒ -C=C-H or Aromatic-CH3
C. 7.3 (2H, d) ⇒ Aro.-H
D. 8.0 (2H, d) ⇒ Aro.-H
E. 11.0 (1H, s) ⇒ -COOH
The science part because the science is particularly of science
Im not sure but i think its hbr. i hope im right and i hope this helped,
More the no. of hydrogen ions more is the solution acidic.
pH means the power of hydrogen that determines the concentration of hydrogen ions or the level of acidiy or basicity of a solution.
so more the hydrogen ions more will be the Power of Hydrogen (pH) and thus more wil be the acidity.
