Question

Alkalis have a slippery feel.
a) True
b) False

Answer 1

Alkalis have a slippery feel due to the presence of compounds that act as bases, such as soaps.

Step-by-step explanation:

Alkalis are known to have a slippery feel, so the statement 'Alkalis have a slippery feel' is True. One reason for this is that alkalis, such as soaps, contain compounds that act as Brønsted-Lowry bases. These bases accept protons from water, forming excess hydroxide ions, which contribute to the slippery feeling of alkalis.
