00:01
So we have given a neutralization reaction here.
00:03
So neutralization reactions are those where acid reacts with base to form salt and water now so we have given here hno3.
00:12
So that is nitric acid which reacts with barium hydroxide so nitric acid is the strong acid and barium hydroxide here we have oh whole twice so that is a strong base and they react with each other to form salt and water so the salt is barium nitrate and water now balancing this reaction.
00:52
So now if i multiply this by 2 okay, so then we have equal number of the nitrogen atom right and and we have then if i multiply this by 2 so we have 3 multiplied by 2.
01:12
So this is 6 oxygen atom plus 2 8 and here 3 multiplied by 2 6 plus 2 oxygen atom 8 so oxygen atoms are equal and now 2 hydrogen atom plus 2 hydrogen atom 4 hydrogen atom on left side and then 2 multiplied by 2 4 hydrogen atoms on right side 1 barium atom on each side.
01:35
So equation is balanced so we can say that 2 mole of nitric acid reacts with 1 mole of barium hydroxide to form 1 mole of barium nitrate and that will be 2 mole of water.
01:54
Okay.
01:55
So now first of all number of moles of barium hydroxide so that will be okay, so number of moles so that will be equal to molarity multiplied by volume this is because we know that molarity or molar concentration that is the number of moles of solute dissolved in one liter of solution...
