The concentration of ca 2 in blood plasma in equivalent if its concentration is 0.0080.
Concentration means the amount of or parts in terms of the alternative components. For acid–base reactions, the equivalent weight of an acid or base is the mass which materials or reacts with one mole of hydrogen
In chemistry, equal weight (additionally known as gram equal is the mass of 1 equivalent, that is the mass of a given substance as a way to integrate with or displace a fixed amount of any other substance. The equivalent weight of an detail is the mass which combines with or displaces 1.008 gram of hydrogen or eight. Zero grams of oxygen or 35.five grams of chlorine. those values correspond to the atomic weight divided through the usual valence for oxygen as example that is sixteen.
Charge on one Ca 2+ ion = + 2 .
Concentration of calcium ion = 0.0040M
⇒ Concentration of Ca 2 + in blood plasma = 0.0040 × 2
= 0.0080 equivalent Ca 2 answer

NaOH is hygroscopic
Explanation:
- A standard solution is a solution of known molarity or concentration.
- Standard solutions are used in determining the stoichiometric amount of desired species in an experiment.
- A solution of NaOH is not a standard solution because NaOH is hygroscopic in nature.
- By this, NaOH absorbs moisture from the atmosphere in considerable amount.
- This implies that one must find an air free environment to store and use the compound and accurately quantify it.
- This is why a solution of NaOH is standardize with a primary standard.
