That is really interesting, thank you Flava! I never really got what the buffer solutions were for before!

So, Flava... I just bought a Hanna pH tester and it doesn't calibrate with the pH 10 solution but it still calibrates with the pH 7 solution. As I am in Australia and I bought it from the US it is really hard and pricey to get sent a replacement. Plus I am still waiting to hear back from the place I bought it... I think they are ignoring me now! Do you think I should just test if it is working by checking something with a higher pH than 7?

bec- sure test something higher! Like I test semen (lol) and it's always over 8 so I know it's working.
Sorry I don't know why it's not working with the 10 I never had one.

yeah we need them and put the meter on the exact same number 1 low 1 high so you know when you test it's reading the correct pH .
