Which gas is always given off when an acid solution is electrolysed?
Hydrogen gas is always given off when an acid solution is electrolyzed.
How do you find moles of hydrogen?
To find the moles of hydrogen, you can divide the given mass of hydrogen by its molar mass. The molar mass of hydrogen is approximately 1 g/mol. So, moles of hydrogen = mass of hydrogen (in grams) / molar mass of hydrogen (approximately 1 g/mol).
How can one test for hydrogen in a given sample?
One can test for hydrogen in a given sample by using a hydrogen gas sensor or by conducting a flame test, where hydrogen gas is ignited to produce a characteristic pop sound.
Why does calcium gluconate given after the fourth dose of blood transfussion?
correct me if im wrong... it's because each unit of blood contains citrate. it acts as a chelating agent and anti coagulant, thus cause hypocalcemia. another, it will prevent citrate toxicity because the liver metabolizes this slowly. each unit may contain about 3g of citrate. am i right?
What gas is given off when magnesium reacts with sulfuric acid?
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
What is equivalent weight of disodium EDTA?
Well, honey, the equivalent weight of disodium EDTA is approximately 292 grams per mole. It's just a fancy way of saying how much of the compound is needed to react with one equivalent of a given reactant. So, if you're looking to do some chemistry magic, there's your answer.
How much gm of disodium EDTA to prepare O5 M disodium EDTA?
To prepare a 0.5 M solution of disodium EDTA, you would need to calculate the molar mass of disodium EDTA (approximately 372.24 g/mol) and then use the formula: (given concentration x volume in liters) / molar mass = mass needed. So, for 0.5 M solution: (0.5 mol/L x 1 L) / 372.24 g/mol = 0.00134 kg or 1.34 g of disodium EDTA is needed.
