What does pH stand for?

[Sid]

Was on the Chase last night.

Question is

 

[Guleesh]

I better google it before I answer to make sure I don't make a fool of myself.........

Spoil sport!

You’ve missed the word “of” out of your choices.

 

[Cab-over Pete]

Although I do concede you’re only actually asking about p and H

 

[tr250]

I’ve answered but I’ve no idea if I’ve got it right glad @Cab-over Pete seems to know

 

[Cab-over Pete]

No, I just know there should be an “of” in there somewhere!

A customer asked me if it stood for the following:

Below 6.3 Pete’s Happy

Above 6.6 Pete’s Huffy

I googled, then answered......... now I feel bad for cheating

A level Chemistry.

Power of 10 concentration of H+ ions. It's a log scale.
That's why it takes a lot of lime to make a difference if you let it get low.

 

[PSQ]

I always thought it was Power of Hydrogen...

 

[7610 super q]

Power harrow the arse out of your soil.....

 

[Cab-over Pete]

I didn’t study A level chemistry and it was the only subject I just scraped through with an O level “D”.

I did well in everything else, but chemistry just confuzzled me. I think I only understood the pH bits because I had stood at the back of Dads Marina van helping him sample!

Thats what I've always said.
So can I say, None of the above.

 

[Bogweevil]

You are all wrong; puissance de hydrogen

Without google, and something I was taught about 30 years ago, it’s the negative power of the hydrogen ion concentration in moles per litre, to the base of ten. There’s an opposite scale pOH which runs 14-1 v/v pH’s 1-14.

8/10. It’s the negative power.

 

[Nearly]

8/10. It’s the negative power.

That makes sense. It was 30 years ago.

 

[SteveHants]

Potential because of variations in dissociation, if I remember correctly.

 

[Nithsdale]

I always thought it just meant phertility...

 

[penntor]

It's the negative log of the hydrogen ion concentration.
