A solution with a pH of 11 has a [H+] of:<br> 11<br> 1 x 10-3<br> 1 x 10-11<br> 1 x 1011<br> 1 x 103
serious [3.7K]

A solution with a pH of 11 has a [H+] of 1.0\times 10^{-11}

Option B is correct option.

Step-by-step explanation:

A solution with a pH of 11 has a [H+] of= ?

pH=?

Concentration of H+ [H+]= ?

Formula used: pH=-log[H+]

Putting values and finding [H+]

pH=-log[H+]\\\,[H+]\,=10^{-pH}\\\,[H+]\,=10^{-11}\\\,[H+]\,=1.0\times 10^{-11}

So, A solution with a pH of 11 has a [H+] of 1.0\times 10^{-11}

Option B is correct option.

valiantina purchased 200 beads dor 48$ if she needs 25 more beads how much will she pay if she is charged the same rate?
Umnica [9.8K]
First find out how much each bead costs. In this case, it is .24 (48/200=.24) Now you simply multiply .24 by 25, equaling 6. She will have to pay 6 more dollars.
