If they have a long halflife, you can tell how much time has gone by since the element last has changed on earth.
Pb(NO3)2 + 2KCl ------) PbCl2 + 2KNO3
Pb+2 + 2Cl- ---------) PbCl2
The pH of a solution depicts the alkalinity or the acidity of the components of the solution and is given as a negative log function of hydrogen ions.
The pH of the solution is:
2
The pH can be estimated as:
- Ionic equation of reaction is written as:
- The mole ratio between HCl and = 1 : 1
- Concentration of = 0.01 M
Therefore, 2 is the pH of the solution.
