Can magnesium float in acids?
no, magnesium never floats in acids...........
What three things should you always do when handling acid or alkali in a lab?
Only three? Wear Goggles Wear protective clothing Have neutralising soluton to hand Plus depending on the reaction to take place - use a fume cupboard or breathing mask, ALWAYS ADD ACID (and alkali) to water, never other way around etc. Some acids are not so much corrosive as highly toxic so again different requirements.
Why should aluminum pans never be cleaned with washing soda?
Because Aluminium is amphoteric and reacts with a strong base and with a strong alkali. NaOH is that strong alkali. Once the soda gets through the AlO layer on the aluminium the soda will react violently giving off toxic gas in some cases or Hydrogen gas if initially mixed with water.
Do acids taste sharp or bitter?
Acids taste sour and bases taste bitter. Bases and Bitter both start with 'B', so I never confuse.

Are Jellyfish stings alkali?
It's alkali...treated with veniger ( or urine). water works
Is it true that alkali metals are never found as uncombined elements?
true
What kind of ions do alkali metals form?
Alkali is a base that dissolves in water. It is highly reactive, but never found in elemental forms of nature.
Alkali metals are extremely reactive and therefore are never found in?
Alkali metals are extremely reactive and therefore are never found in their metallic state - only in compounds. As an example sodium metal is never found in nature only as compounds like salt etc.
What gas is chemically similar to alkali metals?
(A similar relationship exists in Group 1, which includes hydrogen and the alkali metals. All have the same valence configuration, but hydrogen is never included as a member of the alkali metals family.)
Why are the alkali metals never used as a structural material?
Alkali metals tend to react quite violently with water, so if it rained any structure built out of them would be destroyed.
How are acids used in manufacturing?
They are not. They never were, and they never will be. Now cry little college student, cry.
Which one molecule never contain phosphate?
Amino acids.
