What is the difference between water and hydroxide?
Water (H2O) is a molecule composed of two hydrogen atoms and one oxygen atom. Hydroxide (OH-) is a polyatomic ion composed of one oxygen atom and one hydrogen atom, carrying a negative charge. In water, hydroxide ions can exist as a result of the dissociation of water molecules.
How do you find solubility of carbon dioxide in sodium hydroxide?
To find the solubility of carbon dioxide in sodium hydroxide, you can conduct an experiment where you bubble carbon dioxide gas through a solution of sodium hydroxide and measure the amount of carbon dioxide that dissolves in the solution. You can then calculate the solubility of carbon dioxide in sodium hydroxide by dividing the amount of CO2 that dissolves by the volume of the solution.
What is the purpose of titrating sodium hydroxide with an acid solution?
The purpose of titrating sodium hydroxide with an acid solution is to determine the concentration of the acid solution. By carefully adding the acid solution to the sodium hydroxide until the reaction reaches equivalence, the amount of acid needed can be used to calculate its concentration.
What is the difference between alkaline acidic and neutral?
Alkaline substances have a pH above 7, acidic substances have a pH below 7, and neutral substances have a pH of 7. The difference lies in the concentration of hydrogen ions: alkaline substances have fewer hydrogen ions, acidic substances have more hydrogen ions, and neutral substances have an equal amount of hydrogen ions and hydroxide ions.
Does the acid increase the concentration of hydrogen ions in the solution?
The pH increases. There are two ways to think about this. First, adding hydroxide ions is the same as adding a base, and a base will cause the pH of a solution to become more basic, i.e. increase. Second, hydroxide ions will react with hydrogen ions in the solution to neutralize them, decreasing the concentration of hydrogen ions. Since the pH scale is a negative logarithmic scale, a decrease in the concentration of hydrogen ions means an increase in pH.
What will a complete neutralized solution will contain?
salt ions and water and an equal amount of hydrogen and hydroxide ions.
What is the appropriate justification of why pure water is neutral?
YES, because of equal amount of hydrogen and hydroxide ions in the solution.

What other acids and alkalis are there?
Acids are "H+ donors"; they posses hydrogen ions that (in an aqueous solution) covalently bond with hydroxide ions (from a base in an aqueous solution) to form water. Some examples are: H2S, hydrosulphuric acid HF, hydrofluoric acid HPO4, phosphoric acid HCl, hydrochloric acid ** An Alkali, as you are referring to, is a base. They possess hydroxide ions that (in an aqueous solution) covalently bond with hydrogen ions (from an acid in an aqueous solution) to form water. A few examples: NH4OH, ammonium hydroxide NaOH, sodium hydroxide Mg(OH)2, magnesium hydroxide ** There are a limitless amount of alkali and acid possibilities; you just need to be able to name and balance the one you want correctly.
What happen to limewater when you mix it with hydrogen?
When you mix limewater (calcium hydroxide solution) with hydrogen gas, no immediate reaction occurs. However, over time, the hydrogen gas may dissolve in the limewater forming a very small amount of hydrogen hydroxide. This reaction is very slow and may not be observed in real time.

Alkaline substances have a pH above 7, acidic substances have a pH below 7, and neutral substances have a pH of 7. The difference lies in the concentration of hydrogen ions: alkaline substances have fewer hydrogen ions, acidic substances have more hydrogen ions, and neutral substances have an equal amount of hydrogen ions and hydroxide ions.
Colors of sodium hydroxide in phenolphthalein?
Sodium hydroxide in phenolphthalein solution appears as a bright pink color when the solution is basic due to the presence of hydroxide ions. Conversely, in neutral or acidic solutions, the color fades to become colorless.
How could you determine the amount of sodium hydroxide found in the commercial cleaner like Clorox?
One way to determine the amount of sodium hydroxide in a commercial cleaner like Clorox is by using acid-base titration. By titrating a known volume of the cleaner solution with a standardized acid solution (e.g., hydrochloric acid) using a pH indicator or a pH meter, the amount of sodium hydroxide present in the cleaner can be calculated based on the volume and concentration of the acid solution used.
Does the acid increase the concentration of hydrogen ions in the solution?

What volume in mLs of 0.100 M sodium hydroxide solution must be added to 20.0 mL of 0.08 M sulfuric acid solution to reach the end point?
To neutralize the sulfuric acid completely, you need a 1:2 molar ratio of sodium hydroxide to sulfuric acid. Therefore, you would need to add twice the amount of sodium hydroxide compared to the amount of sulfuric acid, which is 40.0 mL of the sodium hydroxide solution.
