Name that
Name 3 bases
soap, eggs, baking soda, laundry detergent
Fruits and juices are examples of what?
acids
7.1-14
TRUE or FALSE: Both acids and bases can be dangerous.
True - but usually only STRONG ones.
(1) What is texture of a rock? (2) What are the two main types?
(1) describes the way its grains fit together, (2) Crystalline & Fragmental
What is the number range of an acid?
1-6.9
Which substances are reactive with metals?
ACIDS (that's why you can clean stuff with soda, lemon, or vinegar)
Which feels slippery - acids or bases?
What happens when you add an acid to a alkali substance?
the pH of the solution is lowered
What is the differences between crystalline & fragmental? Give examples
CRYSTALLINE - tightly fitting (interlocking) crystals that are NOT porous (has pores, can soak up water), ex. Granite; FRAGMENTAL - fragments/grain don't fit together neatly, more porous, ex. sandstone
Name 3 acids
grapes, milk, lemon, tomatoes, bananas, stomach, vinegar
What substance is neutral?
water
Which are cleaning products - acids or bases?
BOTH
How can using acids be dangerous?
Never swallow acids, as they can corrode (essentially destroy) your organs = severely death. Acids below 4 can cause you chemical burns.
What are the two ways that sedimentary rock forms?
COMPACTion (pressure forces layer of grains together) and CEMENTation (water leaves behind materials that bind together the layers)
a measurement of the strength of an acidic or basic solution (=measurement of hydrogen (H+) concentration)
What compound do BASES produce when dissolved in water?
OH-
On litmus paper, what color would vinegar be?
Red (acid)
What is the name of a reaction between an alkali and an acid?
NEUTRALIZATION REACTION AND IT USUALLY RESULTS IN THE FORMATION OF A SALT AND WATER
sedimentary rocks under very high heat and/or pressure = chemical reactions = crystals form (metamorphic rock)
What compounds do ACIDS produce when dissolved in water?
Hydrogen ions (H+)
Which conducts electricity - ACIDS or BASES?
Both - but only if they are STRONG (not weak)
Acids taste ____ and bases taste ________
sour (acids bc H+) ... bitter (bases bc OH-)
What is an alkali?
a base that dissolves in water
Name the 4 characteristics of metamorphic rock.
(1) made of tiny crystals, (2) usually non-porous, (3) often have bands of minerals running through them, (4) no fossils inside (destroyed)
