A.
RbOH is a base because its pH is greater than 7.







B.
HCl is a base because it is the lowest number on the pH scale.







C.

HIO3 is a base because its pH is closest to 7.








D.
HBr is a base because its pH falls between 1 and 7.

Answer 1

@Pawtpie

Answer 2

So on the pH scale, 7 is neutral.

Below 7 are acids and above 7 are bases.

Answer 3

what is rbOH

Answer 4

If we look at the image, RbOH has a pH of about 8 or so

Answer 5

never mind i found out

Answer 6

but thanks

Answer 7

nooo problem :)

Answer 8

is it B @Pawtpie

Answer 9

HCI can't be a base on the pH scale because if it is the lowest number then it is way below neutral 7 and highly acidic

Answer 10

oh

Answer 11

then D

Answer 12

If HBr is between 1 and 7, then it is an acid or neutral. Bases are between above 7 and 14

Answer 13

so it is

Answer 14

Not C because if HIO is closest to 7 it is more neutral than a base

Answer 15

oh nvm stupid me

Answer 16

So it should be?

Answer 17

A

Answer 18

Yes, simply because it's pH is above 7, and is a base :)

Answer 19

thank you again

Answer 20

no problem :)

Answer 21

your a big help
