Answer:
One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it.
Explanation:
Answer:
Reactive and lose 1 electron
Explanation:
Answer:
The calculated concentration of HCl will be less than actual.
Explanation:
Suppose during titration, the <em>HCl</em> was taken in burette and the <em>NaOH</em> in the volumetric flask.
Now we will use equivalence formula for the calculation of concentration of HCl.
Where L.H.S is for hydrochloric acid and R.H.S is for sodium hydroxide. The terms N and V represent normality and volume respectively.
If we calculate for
We see that if the volume of the HCl is greater then the concentration of the HCl will be reduced.
PH is a measure of the concentration of H+ ions are free in solution. It is defined as pH = -log([H+]).
If you replace pH with y and [H+] with x, you get the function y = log(x). If you analyze how this function changes as you increase x, this will show you how pH varies as X changes. Remember, H+ makes a solution more acidic!
