The pH of the solution is used to estimate the acidic and the alkaline condition. The pH paper can be used to determine the conditions. The compound with pH 13.3 is basic.
<h3>What is pH?</h3>
The concentration of the hydrogen or the hydroxide ion in the water gives the estimate of the pH. The potential and the amount of hydrogen decide the acidic and the basic compound.
The pH scale ranges from 0-14 where the scale of 0-6 is acidic, 7 is neutral and 8-14 is basic. If the substance shows a pH of 13.3 then it will lie in the basic range.
Therefore, the compound with a pH of 13.3 is basic.

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:17.955atm
Explanation:Pv=nrt
P= nrt/v
P= 7.25*0.08205*360/11.90
P= 214.1505/11.90
P=17.995atm
Answer:
Catalysts
Explanation:
Catalysts lower the aviation energy.
<u>Answer:</u> The standard potential of the cell is 0.77 V
<u>Explanation:</u>
We know that:
![E^o_{Ni^{2+}/Ni}=-0.25V\\E^o_{Cu^{+}/Cu}=0.52V](https://tex.z-dn.net/?f=E%5Eo_%7BNi%5E%7B2%2B%7D%2FNi%7D%3D-0.25V%5C%5CE%5Eo_%7BCu%5E%7B%2B%7D%2FCu%7D%3D0.52V)
The substance having highest positive
reduction potential will always get reduced and will undergo reduction reaction.
The half reaction follows:
<u>Oxidation half reaction:</u> ![Ni(s)\rightarrow Ni^{2+}(aq)+2e^-](https://tex.z-dn.net/?f=Ni%28s%29%5Crightarrow%20Ni%5E%7B2%2B%7D%28aq%29%2B2e%5E-)
<u>Reduction half reaction:</u>
( × 2)
To calculate the
of the reaction, we use the equation:
![E^o_{cell}=E^o_{cathode}-E^o_{anode}](https://tex.z-dn.net/?f=E%5Eo_%7Bcell%7D%3DE%5Eo_%7Bcathode%7D-E%5Eo_%7Banode%7D)
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
Putting values in above equation follows:
![E^o_{cell}=0.52-(-0.25)=0.77V](https://tex.z-dn.net/?f=E%5Eo_%7Bcell%7D%3D0.52-%28-0.25%29%3D0.77V)
Hence, the standard potential of the cell is 0.77 V
