Value of pH

[Riya Sood 4G]

Can the value of pH every be negative ?

[kim 2I]

Yes. It is possible to have a negative pH. In fact, it is possible to go beyond the known 0 to 14 pH scale.

It's definitely possible to find a negative pH value. Many acids with a concentration of hydrogen ions greater than a molarity of 1 will be calculated to have a negative pH.

[Callum Guo 1H]

yes it could go below negative. The way you calculate ph is -log[h+]

[Tyler Angtuaco 1G]

It can be, such as when the concentration of hydronium is greater than one, but is uncommon.

[Verity Lai 2K]

Yeah the pH can be negative and it can go past 14 but I don't think we need to worry about anything but what's between 1-14 for this class.

[Louise Lin 2B]

It's possible to calculate a negative pH, but in practice in a lab, negative pH can't really be tested for.

[405398682]

Yes, pH value can go below 0 and go above 14, but I think the negative pH is not our class focus.

[Aarushi Solanki 4F]

Yes, this is possible when the H+ concentration is greater than 1.
