Question

A student uses an indicator to measure the pH of a solution. The indicator shows a pH of 7. What must be true of this solution?

Answer 1

the concentration of the H3O+ is equal to the concentration of the OH-

Answer 2

\(\bf\Huge Welcome~to~\color{#00B4ff}{Open}\color{#7cc517}{Study}~!!!\)

Answer 3

The solution has equal amounts of hydrogen and hydroxide ions. they nuetralise each other giving the ph of 7.

Answer 4

If it helped..Please click "best response"..next to my comment..:)

Answer 5

pfff... you know its the Hydronium concentration not the hydrogen concentration

Answer 6

huh?

Answer 7

its when the Hydronium concentration equals the Hydroxide concentration not when Hydrogen concentration equals the Hydroxide concentration

Answer 8

The height of a coin dropped from a tall building is modeled by the equation d(t) = 4.9t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 3 to t = 6 represent

Answer 9

lol out of no where comes OP

Answer 10

lol im sorry i already answered the first question already

Answer 11

It's neutral isn't it? @Kainui From what I remember in grade 7 lol, pH of 7 was considered neutral, that's what milk/ water had.

Answer 12

yes @iambatman , but its technically what i said

Answer 13

can someone answer this

Answer 14

Oh sorry, I didn't read any of the comments haha.

Answer 15

alright @rayray15 im pretty sure rate of change is this equation\[\Delta Y/\Delta X\] or otherwise known as the change in y divided by the change in x

Answer 16

hate to break this to you as well, but milk is slightly acidic :P

Answer 17

will u plz read my comment again?
it says,
they "nuetralise" each other by giving the ph of 7..
