How can you make 500ml of 0.8M HCl solution from 10M HCl and water?
Amount of HCl is 500cm^3 of .8M HCl = .8 x 500/1000 = 0.4 mol. Volume of 10M acid to give 0.4 mol = .4/10 = 0.04dm^3 = 40cm^3 Add 500 - 40 = 460 cm^3 of water. Caution : 10M HCl is highly corrosive and should be handled with care.
How do you determine the number of kilograms of CaCO3 needed to neutralize 500 L of 1.40 M HCl?
CaCO3(s) + 2 HCl(aq) --> CaCl2(aq) + CO2(g) + H2O(l) 500 L * (1.40 mol HCl/1 L HCl) * (1 mol CaCO3/2 mol HCl) * (100.09 g CaCO3/1 mol CaCO3) = 35031.5 g CaCO3 35031.5 g * (1 kg/1000 g) = 35.0315 kg Therefore, about 35.03 kilograms of calcium carbonate is needed to neutralize 500 liters of 1.40 M hydrochloric acid.
How do you prepare 500 ml 1N hcl from 10N HCl?
For 1 Liter you should take 88.8 mL concentrated HCL (be carefull) and add it to 900 mL water, and finally - after mixing- fill this up to 1000 mL with distilled water. (REMEMBER: ALWAYS ADD ACID TO WATER! -1N in 250 ml : add 22.2 mL to about (or less than) 225 mL water and dilute to final volume = 0.25L
How do you make 600 mL of a 1 molar solution of HCl using a 6 molar stock solution?
combine 100 mL 6 M HCl with 500 mL H2O
What is the molality of a solution that contains 31.0 grams of HCl in 500 grams of water?
31 g of HCl divided by the molar mass of HCl to find how many mols. HCl --> H(1) + Cl(1) = molar mass of HCl 1.008(1) + 35.45(1)= 36.428 molar mass 31/36.428= 2.97 which is the mols of solute The mols of solute divided by kg of solute = molality 2.97/.500= 1.7 molality
What product do all neutralization reactions have in common?
They all produce water, and a type of salts. NaOH + HCL ---> H2O + NaCl KOH + HCl ---> H2O + KCl
Is ciprofloxacin hcl safe for a senior to use-500mg?
should a senior(84) take 500 mg. of ciprofloxacin since I cant take bactrim.
How many moles HCl in 8.3 g HCl?
8.3 grams HCl (1 mole HCl/36.458 grams) = 0.23 moles HCl ------------------------
you have 500 ml of a 1.5 m hcl solution (acid). if there is 250 ml of koh solution present (base). what will be the molarity of the koh (base)?
675
How can you check the purity of Kcl?
If you melt the HCl, and it melts at the proper melting point for HCl, then it is a pure substance. If not, it has been mixed with something else, which has altered the purity of the HCl.
How do you write HCl in water?
This is how you write HCl (Hydrochloric acid) in water: HCl (aqueous) or short form HCl(aq)
What is the symbol for hydrochloric acid?
The chemical formula (not symbol) of hydrogen chloride is HCl; for a diluted solution you can use "HCl dil." but this isn't a standard formula.
