The feeling was that with such a high pH, it could almost cause something analogous to a chemical burn.

Exposure to cold or high pH inhibits its growth.

But phenolphthalein's pink endpoint is actually at a pretty high pH.

This implies that the high pH is due to the addition of a strong base rather than to natural conditions.

Although its activity is increased by higher pH, the inhibitory effect of zinc also increases.

It is a base, meaning it has a very high pH.

Limestone cliff faces, which have a high pH, are particularly affected in this way.

The main concern would be the high pH - probably 11-13 - due to excess sodium hydroxide.

This salt bridge was found to increase the thermostability of the enzyme at such high pH.

Rye is a strong plant that can survive in soil with a high or low pH.
