Give a acid-base pairs which produce Na2CO3 as a salt
H2CO3 = carbonic acid
NaOH = sodium hydroxide
H2CO3 + 2NaOH ==> Na2CO3 + 2H2O
To find acid-base pairs that can produce Na2CO3 as a salt, we need to look for acids that can donate a proton (H+) and bases that can accept a proton. Na2CO3, also known as sodium carbonate, is a basic salt that forms when a strong base reacts with a weak acid.
One possible acid-base pair that can produce Na2CO3 is:
Acid: H2CO3 (carbonic acid)
Base: 2 NaOH (sodium hydroxide)
The reaction between carbonic acid (H2CO3) and sodium hydroxide (NaOH) can be represented as follows:
H2CO3 + 2 NaOH → Na2CO3 + 2 H2O
In this reaction, the acid (H2CO3) donates two protons (H+) to the base (NaOH), forming water (H2O) and sodium carbonate (Na2CO3) as the salt.
It's important to note that there can be other possible acid-base pairs that can also produce Na2CO3 as a salt, depending on the specific reactants used.
