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.
What are the different salts produced by reacting sodium hydroxide with phosphoric acid?
The reaction between sodium hydroxide and phosphoric acid produces sodium dihydrogen phosphate (NaH2PO4) and water.
How can you calculate the concentration of a phosphoric acid solution from the titration with sodium hydroxide?
You can calculate the concentration of a phosphoric acid solution by determining the volume of sodium hydroxide needed to neutralize it in a titration. The molarity of the sodium hydroxide solution and the balanced chemical equation for the reaction will allow you to find the moles of phosphoric acid present, hence the concentration.
What happens when you mix sodium hydroxide with phosphoric acid?
When sodium hydroxide is mixed with phosphoric acid, a neutralization reaction occurs, resulting in the formation of sodium phosphate and water. The reaction can be written as: 3 NaOH + H3PO4 → Na3PO4 + 3 H2O
How do you prepare 1.0L of 0.1M of sodium hydroxide from solid sodium hydroxide pellets?
To prepare 1.0L of 0.1M sodium hydroxide solution, you need to dissolve 4 g of solid sodium hydroxide pellets in water and then dilute the solution to 1.0L. Measure 4 g of sodium hydroxide pellets on a balance, dissolve them in less than 1.0L of water, and then make up the volume to 1.0L with additional water. Be cautious as sodium hydroxide is a caustic compound – wear appropriate safety gear and handle with care.
Can you name some Acids and Hydroxides?
Hydrochloric acid Sulfuric acid Phosphoric acid Sodium hydroxide Calcium hydroxide Potassium hydroxide
What is the formula of two salts formed from sodium hydroxide and phosphoric acid?
NaOH + H3PO4 --> Na3PO4 NaOH + H3PO4 -->
How do you prepare a 0.4 molar solution of sodium hydroxide from 96 percent sodium hydroxide pellets?
16.5g 97% pure NaOH pellets dissoved in 1 litre of distilled
What volume of 0.200 molarity phosphoric acid will react completely with 50ml of 0.100 molarity sodium hydroxide?
Phosphoric Acid dissociates to give off 3H+ ions, meaning that one mole of Phosphoric acid reacts with three mols of sodium hydroxide. Using the equation n = c x v n = 0.1 x 0.05 =0.005 mols of OH ions in the solution therefore there are 0.005/3 = 0.00167 So the volume of phosphoric acid - v = n/c v = 0.00167/0.2 v = 0.00835 l = 8.4ml of Phosphoric Acid reacts completely with Sodium hydroxide
What is dilute sodium hydroxide?
Dilute sodium hydroxide refers to a solution containing a lower concentration of sodium hydroxide in water. It is commonly used in various industries for its alkaline properties, such as in cleaning agents or as a chemical reagent in laboratories. Dilute sodium hydroxide is less concentrated than its solid or more concentrated liquid forms, making it safer for certain applications.
How is sodium hydroxide available in the laboratory?
Usually in the form of tiny spherical white pellets.
What is the titration curve of phosphoric acid and sodium hydroxide?
The titration curve of phosphoric acid and sodium hydroxide shows the pH changes as the two substances are mixed in a controlled manner. At the start, the pH is low due to the acidic nature of phosphoric acid. As sodium hydroxide is added, the pH gradually increases until it reaches a plateau at each equivalence point, where the acid and base have completely reacted. The curve typically shows three distinct equivalence points corresponding to the three acidic hydrogen atoms in phosphoric acid.
