When sodium hydroxide dissolve in water estimate the temperature change when the amount sodium hydroxide is doubled?
When sodium hydroxide dissolves in water, it undergoes an exothermic reaction, releasing heat. If the amount of sodium hydroxide is doubled, the same amount of heat will be released, resulting in an increase in temperature. The specific temperature change would depend on the initial amounts and concentrations of the sodium hydroxide and water.
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.
Why sodium hydroxide solution contains sodium carbonate?
Sodium hydroxide solution may contain sodium carbonate due to the absorption of carbon dioxide from the atmosphere. Sodium hydroxide can react with carbon dioxide to form sodium carbonate over time, especially if the solution is exposed to air. This can result in a small amount of sodium carbonate being present in the solution.
How many grams of sodium hydroxide will react with 150g of phosphoric acid sodium phosphate is one product?
To find the amount of sodium hydroxide needed to react with 150g of phosphoric acid, you first need to determine the balanced chemical equation between sodium hydroxide and phosphoric acid. From there, you can use stoichiometry to calculate the amount of sodium hydroxide needed.
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 Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?
To completely precipitate 86.9mg of magnesium from seawater, you would need to add an equal molar amount of sodium hydroxide. The molar mass of magnesium is about 24.3 g/mol, so 86.9mg is equivalent to about 3.57 mmol of magnesium. You would need the same amount of mmol of sodium hydroxide to completely precipitate the magnesium.
How could you determine the amount of sodium hydroxide found in the commercial cleaner like Clorax?
You would need to perform a quantitative chemical analysis, such as a titration. A titration involves adding a known concentration of an acid to the cleaner solution until the reaction is complete. By measuring the volume of acid needed to neutralize the sodium hydroxide in the cleaner, you can calculate the concentration of sodium hydroxide present.
How is the concentration of hydroxyl ions affected when excess base is dissolved in a solution sodium hydroxide?
The concentration of hydroxyl ions will increase because sodium hydroxide dissociates in water to release hydroxide ions. The excess base will increase the amount of hydroxide ions present in the solution, leading to a higher concentration of OH- ions.
How many moles of sodium sulphate can be formed from two moles of sodium hydroxide?
No amount of sodium sulphate can be formed from sodium hydroxide alone, because sodium sulfate contains sulfur and sodium hydroxide does not. By neutralization with sulphuric acid, one formula unit of sodium sulphate can be formed from two moles of sodium hydroxide, according to the equation 2 NaOH + H2SO4 -> Na2SO4 + 2 H2O.
What is the reaction between sulphamic acid with sodium hydroxide in paracetamol estimation?
In the reaction between sulphamic acid and sodium hydroxide in paracetamol estimation, sulphamic acid reacts with paracetamol to form a colorless solution. The addition of sodium hydroxide then helps to break down the paracetamol into its constituent components, allowing for accurate estimation of the amount present in the solution.
What is sodium hydroxide pH level?
pH level is a measure of acidity, the simplest way to understand it is the lower the pH value the more acid something is, and the higher the pH value the more alkali something is. Finaly a value of pH 7 is neutral (neither acid or alkali).pH does not show the amount of Sodium Hydroxide present, however the pH would increase if Sodium Hydroxide was added because Sodium Hydroxide is alkali.The pH of concentrated (1 M) Sodium Hydroxide is 14.
