Calculate the concentration of the NaOH solution. If 30,0cm3 of a standard oxalic acid[(COOH)2] solution of concentration 0,5 mol.dm-3,is used to neutralize 25,0 cm3 of a sodium hydroxide (NaOH) solution. The balanced chemical equation for the reation is (COOH)2(aq) + 2NaOH(aq...

Chalk is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite. Calcite is calcium carbonate, CaCO3. It forms under relatively deep marine conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-...

Hey yall! i am working on a lab where we used NaOH solid (pellets) and 1.0M of NaOH solution. i was wondering is Sodium Hydroxide a substance that reacts with the enviroment? because maybe that could be like a source of error right? so basically i am wondering if both or one ...

How much sodium hydroxide, at what concentration, do I need to add to 500 mL of 0.1 N HCL to obtain pH 6.8. How do you calculate this? pH = -log(H^+) M HCl = N HCl mols = M x L. After you know mols HCl you have, then make a solution of NaOH and calculate how much of that must ...
