How many milliliters of 0.130 M HCl are needed to completely neutralize 41.0 mL of 0.107 M Ba(OH)2 solution?
Anvisha [2.4K]

54 mL Ba(OH)2x(0.101 mol Ba(OH)2/1000 mL) x (2 mol OH-/ 1 mol Ba(OH)2 )  = 0.0109 mol OH-

                                 

0.0109 mol OH-x (1mol HCl/ 1 mol OH- ) = 0.0109 mol HCl

                                                     

0.109 mol HCl/(0.130 mol/L HCl) =  0.0839 L HCl

0.0839 L HCl * 1000mL = 83.9 mL of 0.130 M HCl

Will platinum (pt) metal react with a lead(ii) nitrate solution?
My name is Ann [436]

To answer this question, we must first look at the reactivity series table. From the table, we can see that those which are located above are the most reactive while those below are less reactive. Which means that elements cannot replace those elements which are above them.

From the series, platinum is below lead, hence there will be no reaction.

 

Answer:

No reaction
