The table shows data from an experiment designed to find a solution that is both an acid and a strong electrolyte. Based on the data, which solution is the best acidic electrolyte. Solution 1, 2, 3, or 4? Thank you!!!

Solution 4 is the best acidic electrolyte

Explanation:

An acidic medium such as a solution has a pH that is less than 7. The acidity of the medium increases with decrease in the pH value. Acidic solutions turn blue litmus solution red. They produce hydrogen ions as positive ions solution as well as a negatively-charged ion.

An electrolyte is a solution which allows electric current to pass through it and in the process is decomposed by the electric current. Electrolytes are able to allow current flow through them because they are composed of negatively and positively-charged molecules known as ions which are responsible for carrying electrical charges. A good electrolyte will be a solution which conducts electricity freely.

Based on the data in the table, the solution that is both acidic and has high electrical conductivity is solution 4. Solution 4 turns blue litmus solution red indicating that it is acidic. Also, it has a low pH of 2.0 indicating that it is very strongly acidic.

Therefore, solution 4 is the correct option.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
