Molarity in the measurement of concentration, it is measured by number of moles of solute present in a liter of solvent.
Molarity = moles/volume
If we have 0.05 Molar HCl solution which means the concentration of that solution is 0.05M, which also refer to the number of H+ ions concentration and measuring H+ ions will give you the PH.
Therefore PH of 0.05 M HCl is …
PH = - log [0.05]
Since 1.3 is in the range of 1 to 7 of PH scale this 0.05 M HCl solution is acid solution since it has acidic PH.
PH is the expression of concentration, depending upon the concentration PH can be acidic PH or basic PH.
PH = - log [H+]
PH scale range from 1 to 14
If the PH concentration is in the range between 1 to 7 then it is acidic PH and if the PH concentration is in the range between 7 to 14 then it is basic PH and 7 is the neutral PH.
Blood has PH range of 7.36 to 7.41 which means blood has basic PH, alteration of PH will lead various disorders which inturn effect the biological system.
If blood PH falls below 7 then it will lead to coma and finally to death.
Blood has buffers to mentain the PH of the blood thus helps to meantain the PH of blood.
