Then he named a little-known chemical which had an acid reaction.

I'm not aware of any acid reactions that release oxygen.

In general, silicic acid reactions are difficult to control.

All simple metal with acid reactions are single displacement reactions.

Tombstone remembered his own acid reaction a moment earlier, when Snowball admitted he was scared.

I am trying to teach 14 year old students about the characteristics of metal and acid reactions and how to use them in their sculptures.

Silver (Ag) on the other hand is below the nitric acid reaction so it will react.

Acid reactions, the formation of salts, and ion exchange are fast reactions.

A well-known hydroxamic acid reaction is the Lossen rearrangement.

They grow in almost any well-drained soil but, like most ornamentals, prefer a soil with an acid reaction.

It is believed by some soil experts that the rainfall leaches out any calcium or magnesium in the soils and causes the acid reaction.

The acid reaction of these soils has almost certainly been ameliorated by the addition of shelly sand from the adjacent machairs.

In acid it forms the sulfate salt liberating H2 gas (the normal metal / acid reaction).

When aspergillic acid reactions with iron trichloride (FeCl), there is the formation of green cupric salt.

There are several Akabori Amino Acid Reactions.

Blackening of the bottom due to HS production may mask the acid reaction (yellow) in the bottom of the tube.

It usually has an acid reaction, owing to the presence of acid phosphates of soda or free uric acid.

They have a strongly acid reaction and their B horizons often contain illuviated sesquioxides of iron and aluminium and organic matter.

Between numbers, Hilda's wisecracking antics and Evadne's acid reactions to her companion's attention-seeking are a rich source of comedy in the act.

Brown earths have a uniformly coloured B horizon, a mull or moder humus type and a moderately acid reaction; usually each horizon merges into the one below.

From the above equations for the solubility product, the hydration reaction and the two acid reactions, the following expression for the maximum [Ca] can be easily deduced:

Little heard, but not altogether absent, were the acid reactions of four years ago from those left out of a dot-com boom that minted hundreds of millionaires in their midst.

LEACHED SOILS are characterised by a uniformly coloured B horizon, by an absence of free lime and by an acid reaction in their A and B horizons.
