Sodium chloride, also known as table salt, is a compound composed of sodium (Na) and chloride (Cl) ions. When dissolved in water, it dissociates into its constituent ions.
When sodium chloride is dissolved in water, it undergoes a process called ionization, where the compound breaks down into its individual ions. In the case of sodium chloride, it dissociates into sodium ions (Na+) and chloride ions (Cl-). This ionization process is responsible for the observed behavior of sodium chloride when it comes into contact with different indicators.
Methyl Orange is an acid-base indicator that changes color depending on the pH of the solution it is in. In acidic solutions, methyl orange is red, while in basic solutions, it is yellow. When sodium chloride is dissolved in water, it does not change the pH of the solution significantly. Since the pH remains relatively constant, the methyl orange indicator does not undergo any noticeable color change. Therefore, the correct answer is option 'C' - No change in color.
Blue litmus paper is a pH indicator that turns red in the presence of an acidic solution and remains blue in a basic or neutral solution. When sodium chloride is dissolved in water, it does not alter the pH significantly. Therefore, the blue litmus paper does not change its color, and the correct answer is not option 'B'.
Similarly, red litmus paper is another pH indicator that turns blue in the presence of a basic solution and remains red in an acidic or neutral solution. Sodium chloride, when dissolved in water, does not significantly affect the pH, so the red litmus paper does not undergo any color change. Therefore, the correct answer is not option 'D'.
In conclusion, when sodium chloride is dissolved in water, it does not cause any significant change in the pH of the solution. As a result, indicators such as methyl orange, blue litmus paper, and red litmus paper do not exhibit any color change when in contact with sodium chloride solution. Hence, the correct answer is option 'C' - No change in color.

The answer is no change in colour because as we know that common salt(sodium chloride) is nuetral(means ph7) and if any substance is nuetral then there is no cjange in colour
