Answer:
We know that pole is the point where the strength of the magnet is maximum. So more and more iron particles will be attracted at poles of a magnet when we bring a magnet near the iron particles. We will observe the crowdness of particles at the ends of magnet. This indicates the presence of two poles in a magnet. Hence poles are present in a magnet in pair. If a magnet is divided into two parts, each part also possesses a pair of poles.
Two properties of a magnet are: A magnet always has two poles: north pole and south pole. Like magnetic poles repel each other and unlike magnetic poles attract each other.
CsCl, when dissolved in water, produces the solution with a ph closest to 7.00.
<h3>What is pH?</h3>
In chemistry, pH, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.
Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions.
The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.
Solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.
Solutions with a pH of 7 at this temperature are neutral (e.g. pure water).
The neutral value of the pH depends on the temperature – being lower than 7 if the temperature increases above 25 °C.
The pH value can be less than 0 for very concentrated strong acids, or greater than 14 for very concentrated strong bases.
