What is the theoretical yeild of HNO3?
The theoretical yield of HNO3 is the maximum amount of nitric acid that can be produced in a chemical reaction based on stoichiometry and assuming 100% yield. It can be calculated by converting the given amount of reactant to moles, using the balanced equation, and then converting moles to mass of HNO3.
What is the pH of a 1.45M HNO3 solution?
The pH of a 1.45M HNO3 solution is approximately 0.14. This is because nitric acid is a strong acid that dissociates completely in water to yield H+ ions.
Which reaction represents an unbalanced neutralization reaction?
HCl + NaOH -> NaCl + H2O is an unbalanced neutralization reaction.
What does nitrogen dioxide dissolved in water yield?
This yields nitric and nitous acid (1 to 1) H2O + 2 NO2 --> HNO2 + HNO3
Why is NaCl extracted with water three times as opposed to only once?
Extracting NaCl with water three times helps to ensure that as much NaCl as possible is extracted from the solid material. Each extraction helps to increase the efficiency of separating NaCl from impurities or other soluble components. By repeating the process multiple times, the overall yield of NaCl is increased, resulting in a purer final product.
What does hcl and nano3 make?
Mixing hydrochloric acid (HCl) and sodium nitrate (NaNO3) will result in the formation of sodium chloride (NaCl) and nitric acid (HNO3). This reaction occurs as a double displacement reaction where the cations and anions switch partners.
What does HNO3 plus CaOH yield?
When nitric acid (HNO3) reacts with calcium hydroxide (Ca(OH)2), it forms calcium nitrate (Ca(NO3)2) and water (H2O) as products.
How will you obtain HNO2 from HNO3?
To obtain HNO2 from HNO3, you can reduce nitric acid (HNO3) using a reducing agent such as sulfamic acid or a metal like copper. The reduction reaction will convert the nitric acid to nitrous acid (HNO2). Make sure to carry out the reaction in a controlled environment with proper safety measures.
What is the percent yield for Na plus Cl2 -- 2NaCl?
Percentage yield is given as:-%yield = (mass of product obtained experimentally/theoretical yield)x100where the theoretical yield is the maximum mass which could possibly be obtained assuming 100% stoichiometry.So, say as an example if you start with 71g of Cl2 then:-mol = mass/Mr Mr of Cl2 = 71mol = 71/71mol = 1 of Cl2This is the limiting reagent, assuming we have at least 46g of sodium, thus we double this number as the reaction is 1:21 mole Cl2---->2moles NaClagain we use:-mole = mass/Mr Mr of NaCl = 58.52 x Mr = mass2 x 58.5 = massmaximum mass of NaCl possible = 117gIf the reaction is carried out and we achieve 100g of NaCl then:-%yield = (100/117) x 100= 85.5%
What is the formula of hydrogen nitrate?
The chemical formula for Hydrogen Nitrate is: HNO3
What is the name of HNO3?
HNO3 is Nitric Acid
Preparation of 1000ppm of standard Sodium solution from NaCl?
1 mg/l = 1ppm1 g/l = 1000 ppmNaCl ----------------> Na+ + Cl-58.5 g NaCl gives 22.989 g Na+(58.5 / 22.989) = 2.545 g of NaCl is required to give 1 g of Na+When 2.545 g of NaCl is dissolved in 1 liter water will yield 1000 ppm of Na+ in NaCl solution.
