In summary, the conversation involves multiple questions regarding acid-base reactions of common household items and the chemical formulas and conjugate acids of various substances. One question discusses net Bronsted equations while another focuses on the pH and conjugate acid of Tums antacid (calcium carbonate). The attempt at a solution includes attempts at writing equations for the reactions, but some of the substances are already dissociated and therefore do not participate in the reactions. The correct answers for the chemical formulas and conjugate acids have not been determined yet.

1.Homework Statement

1.Write net Bronsted equations that show the acid-base reactions of common household items. For polyprotic species (vitamin C, lemon juice, and baking powder), please show only one proton transfer. Remember that spectator ions are not included.

A)Sodium Hypoclorite and H2C6H6O6

B)Sodium Carbonate and HC2H3O2


Another question:

2.Chemical formula and conjugate acid of tums antacid (calcium carbonate) with a pH of 8.5 when reacted with H20

Chemical formula for lithium hydrogenphosphate with a pH of 9.7 and conjugate acid when reacted with water


Homework Equations



Acid + Base -> Conjugate Base + Conjugate Acid


The Attempt at a Solution



A) H2C6H6O6 + NaClO -> HC6H6O6^1- + NaClO^1+

I got the acid and conjugate base right, but its not taking NaClO or NaOCl as Sodium carbonate.

B) HC2H3O2 + Na2CO3 -> C2H3O2^1- + Na2CO3^1+

once again, not taking the base or conjugate acid. I don't know why Na2CO3 is not right for sodium carbonate...

2. Tried CaCO3 for calcium carbonate and it did not like that answer.

Tried H2LiPO4 for lithium hydrogenphosphate and no luck.

Any help appreciated...

First of all - some of these substances are already dissociated before acid/base reactions start. For example sodium carbonate dissociates to Na+ and CO32- - and Na+ is just a spectator.

1. What is an acid-base reaction?

An acid-base reaction is a chemical reaction in which an acid and a base react with each other to form a salt and water. This reaction involves the transfer of a proton (H+) from the acid to the base.

2. How do you identify acids and bases in a chemical equation?

Acids can be identified by their ability to donate a proton (H+), while bases can be identified by their ability to accept a proton. In a chemical equation, acids are typically represented by the presence of hydrogen (H) at the beginning of a formula, while bases are represented by the presence of hydroxide (OH) at the end of a formula.

3. What is the pH scale and how is it used in acid-base reactions?

The pH scale is a measure of the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral, values below 7 being acidic, and values above 7 being basic. In acid-base reactions, the pH scale is used to determine the strength of the acid or base involved.

4. What is the difference between a strong acid/base and a weak acid/base?

A strong acid or base is one that completely ionizes in water, meaning that all of the molecules break apart into ions. A weak acid or base only partially ionizes in water, meaning that some of the molecules remain intact. This results in a stronger reaction for strong acids/bases compared to weak acids/bases.

5. How do you calculate the products of an acid-base reaction?

To calculate the products of an acid-base reaction, first determine which reactants are acids and bases. Then, use the general equation for acid-base reactions: acid + base → salt + water. The products will be a salt, which is a compound made up of the positive ion from the base and the negative ion from the acid, and water.
