Why do we need distilled water in preparation of sodium hydroxide solution sodium carbonate and oxalic acid solutions?
Distilled water is required to prevent impurities from affecting the chemical reactions and accuracy of the solutions. Sodium hydroxide, sodium carbonate, and oxalic acid solutions require pure water to ensure precise concentrations and reliable results. Using distilled water helps avoid contamination and ensures the solutions are properly diluted.

Why do we need distilled water in preparation of sodium hydro-oxide solution sodium carbonate and observe?
Distilled water is used to prepare solutions because it is free of impurities that could react with the chemicals being dissolved and alter the results. In the case of preparing sodium hydroxide or sodium carbonate solutions, using distilled water ensures that the concentration of the solution is accurate and consistent. It also helps avoid unwanted reactions or contamination that could affect the observation or results of the experiment.
Why do you need distilled water in preparation of Naoh solution sodium carbonate and oxalic acid solution?
Distilled water is the closest one can get with conventional methods to pure water, which would be ideal to create solutions. Tap water is typically not used because it contains minerals and other foreign materials that can affect the solution itself, and alter results.
Does sodium hydrogen carbonate have a lower pH than sodium hydroxide?
It depends on the concentrations of these substances. However, sodium hydroxide is a very strong base and therefore is capable of producing solutions with high pH values. On the other hand, sodium hydrogen carbonate is weakly acidic, and is therefore capable of producing solutions that are somewhat less than neutral. (Carbonic acid is itself a weak acid.)
What is the pH of sodium carbonate solutions?
The pH of sodium carbonate solutions is typically around 11-12, making it basic or alkaline.
Distilled water is about the only completely neutral solution. What is its pH?
Almost anything - its not buffered. (Your first statement is false)

Why should base solutions be carbonate free?
Base solutions should be carbonate free because of carbonate interference. They can cause impurities and changes to the concentration in the solutions.
What happen when Sodium hydroxide reacts with carbon dioxide?
When sodium hydroxide reacts with carbon dioxide, sodium carbonate and water are formed. The carbon dioxide gas is absorbed by the sodium hydroxide solution to produce sodium carbonate as a solid precipitate. This reaction is commonly used to capture carbon dioxide in industrial processes or to neutralize acidic solutions.
What is sodium chloride commonly used in?

What reaction causes aqueous solutions of alkali metal carbonates to be basic?
Aqueous solutions of alkali metal carbonates are basic because they undergo hydrolysis in water, producing hydroxide ions that increase the pH of the solution. The carbonate ion reacts with water to form a hydroxide ion and bicarbonate ion, effectively raising the concentration of hydroxide ions in the solution and making it basic.
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What products can you get from salt?
Some important applications of sodium chloride - preparation of sodium, chlorine, sodium hydroxide, hydrogen- soaps fabrication- salts baths- isotonic solutions and other applications in medicine
Which of the solutions were basic Why?
Sodium hydroxide and ammonia are basic solutions because they are both alkalis that release hydroxide ions in water, increasing the concentration of hydroxide ions and raising the pH above 7.
