Answer:
The molarity of the base is 0.2664 M
Explanation:
Firstly, we write the complete and balanced titration reaction.
+ 
→ 
+ 
From the reaction, we can identify that 1 mole of the acid reacted with 2 moles of the alkali (base) to yield salt and water only
We identify the following also from the question;
= 14.80 mL , 
= 25.00 mL , 
= 0.225M and 
= ?
= 1 , 
= 2
We use the relation;
/ = /
Plugging the values, we have ;
(0.225 × 14.80)/1 = ( × 25.00)/2
= (2 × 0.225 × 14.80)/25
= 0.2664 M
Answer:
A
Explanation:
The type of property used to describe a substance is reactivity
Since O almost always has a charge of -2, the oxygen atoms have an overall charge of -8 (-2*4)
Since K has a charge of +1, that brings the overall charge to -7 (-8+1)
Then, in order for the overall charge to be 0, Mn would have to have a change of +7 (-7+7=0)
Hope this helps
