How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?
To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.
How do you make sodium silicate solution?
To make sodium silicate solution, mix silica gel with sodium hydroxide in water. The ratio of silica gel to sodium hydroxide can vary depending on the desired concentration of the solution. Heat the mixture until the silica gel dissolves to form a clear solution.
How do you make a 5 percent water solution of sodium hydroxide?
To make a 5% water solution of sodium hydroxide, you would mix 5 grams of sodium hydroxide with 95 grams of water. This will give you a total of 100 grams of solution, with 5% of it being sodium hydroxide. Remember to always add the sodium hydroxide to the water slowly and with caution due to its caustic nature.
Can I lower the pH of sodium hydroxide with water?
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
What ion is responsible for Make it basic sodium ion or hydroxide ion or hydrogen ion or water ion?
The hydroxide ion (OH-) is responsible for making a solution basic. It can combine with hydrogen ions (H+) to form water (H2O), reducing the concentration of free hydrogen ions and increasing the pH of the solution. Sodium ions (Na+) do not play a direct role in determining the pH of a solution.

What compound sodium hydroxide and water make all together?
Just a solution of sodium hydroxide in water.

How do you make a pure sample of salt?
Sodium hydroxide is an alkali. If you take solutions of hydrochloric acid and sodium hydroxide that have the same concentration, and mix equal volumes of them, the sodium hydroxide neutralises the acid. if you take tests with the solution on universal indicator paper, you will find it has pH7. If you leave the solution to evaporate, you will see crystals of salt. This is the kind of salt you put on your chips but remember not to eat them in a laboratory! =)
How do you prepare 5 ppm sodium hydroxide solution?
To prepare a 5 ppm sodium hydroxide solution, you would need to dissolve a small amount of sodium hydroxide in a larger volume of water. For example, to make 1 liter of 5 ppm solution, you would add 5 mg of sodium hydroxide to the water. It's crucial to accurately measure both the sodium hydroxide and the water to ensure the final concentration is correct.

How do you prepare 1000ppm sodium solution from sodium chloride?
To prepare a 1000 ppm sodium solution from sodium chloride, first calculate the molecular weight of sodium chloride (NaCl). Then, dissolve the calculated amount of NaCl in a known volume of water to achieve a final concentration of 1000 ppm (1 mg/L). Make sure to accurately measure the mass of NaCl and volume of water to ensure the desired concentration is reached.
What does iron sulphate solution and sodium hydroxide solution react to make and are the products aqueous?
Iron sulphate solution and sodium hydroxide solution react to form iron hydroxide, which is initially a precipitate but will dissolve to form a green aqueous solution of iron(II) hydroxide.
How do you calculate of NaOH in solution procedure?
To calculate the concentration of NaOH in a solution, you would typically measure the volume of the solution and the amount of NaOH used to prepare it. Then, you can use the formula: Concentration (in mol/L) = amount of NaOH (in mol) / volume of solution (in L) to determine the concentration. Make sure to convert any given amount of NaOH from grams to moles before calculating.
Why the aqueous solution of sodium acetate is alkaline?
Sodium acetate is a salt formed by the reaction between acetic acid and sodium hydroxide. When dissolved in water, sodium acetate undergoes hydrolysis, releasing hydroxide ions (OH-) which make the solution alkaline. This alkaline property is due to the presence of excess hydroxide ions in the solution.
