Expert Solution

true statements : only two (a) and (e)

b) Basic solutions taste bitter.

e) [H₃O⁺] is less than 1.00 x 10^-7 in a basic solution.

reamining are not correct :

explanation :

a) Acidic solutions taste bitter. (false)

explanation : acidic solutions are taste sour

c) Acidic solutions cause red litmus to change color to blue. (false)

explanation : Acidic solutions cause blue litmus to change color to red

d) Basic solutions cause blue litmus to change color to red.(false)

explanation : basic solutions cause red litmus to change color to blue

e) [H₃O⁺] is less than 1.00 x 10^-7 in a basic solution. (true)

explanation : for basic solution [H3O+] <[OH-]

[H3O+] < 1 .0 x10^-7

f) [OH^-] is less than 1.00 x 10^-7 in a basic solution. (false)

explanation : for basic solution [H3O+] <[OH-]

1.0 x10^-7 < [OH-]
