<u>Answer:</u>
<em>Substances known as </em><u>electrolytes</u><em> are found in blood which includes sodium and potassium.</em>
<u>Explanation:</u>
<em>Electrolytes are electrically charged particles</em> and they help in moving nutrients into the cell and removing waste particles out of the cell. Other <em>functions of electrolytes</em> include maintaining the salt level as well as <em>pH level of the body. </em>
The electrolyte potassium is present in <em>small quantities in the fluid part of blood, namely plasma.
</em>
Regulating body muscle contraction is the main function of potassium. The fluid region outside cells contains a <em>major portion of sodium which maintains the water balance of the body.
</em>
Answer:
The symbol that represent a salt is CaCl2
Explanation:
The CaCI2 is the calcium chloride that an organic compound now a salt having a chemical formula i.e. CaCI2. Also it is non-color cyrstalline solid at the room temperature also it is highly soluble in the water
Therefore as per the given situation the symbol that represent a salt is CaCI2
This is the answer and the same is not provided in the given options
Answer:
The periodic law states “When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties
Answer : The pH of a solution is, 7.28
Solution : Given,
Concentration of hydronium ion,
= ![5.2\times 10^{-8}M](https://tex.z-dn.net/?f=5.2%5Ctimes%2010%5E%7B-8%7DM)
pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.
![pH=-\log (5.2\times 10^{-8})=7.28](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%285.2%5Ctimes%2010%5E%7B-8%7D%29%3D7.28)
Therefore, the pH of a solution is, 7.28
