identify the following formulas as acids, bases or salts:
HCH3COO
NaCL
H2CO3
C6H8)7
Mg(OH)
NaOH
KBr
Sr(OH)2
HNO3
please help :) thanks :)
To identify the formulas as acids, bases, or salts, we need to understand the nature of these substances:
1. HCH3COO: This is the formula for acetic acid. Acetic acid is a weak acid, commonly found in vinegar.
2. NaCl: This is the formula for table salt, sodium chloride. Sodium chloride is a salt since it is a compound formed by the reaction between an acid (hydrochloric acid) and a base (sodium hydroxide).
3. H2CO3: This is the formula for carbonic acid. Carbonic acid is a weak acid that is formed when carbon dioxide dissolves in water.
4. C6H8)7: The formula provided is incomplete. Please check the formula and provide the correct one.
5. Mg(OH)2: This is the formula for magnesium hydroxide. Magnesium hydroxide is a base commonly used in antacids and laxatives.
6. NaOH: This is the formula for sodium hydroxide. Sodium hydroxide is a strong base that dissociates completely in water.
7. KBr: This is the formula for potassium bromide. Potassium bromide is a salt formed by the reaction between an acid (hydrobromic acid) and a base (potassium hydroxide).
8. Sr(OH)2: This is the formula for strontium hydroxide. Strontium hydroxide is a base similar to magnesium hydroxide, commonly used in fireworks and as a reagent in the laboratory.
9. HNO3: This is the formula for nitric acid, a strong acid that dissociates completely in water.
In summary:
Acids: HCH3COO, H2CO3, HNO3
Bases: Mg(OH)2, NaOH, Sr(OH)2
Salts: NaCl, KBr
