What else can I help you with?
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.
Could you use only one indicator to see if a solution is neutral?
Using a single indicator to determine if a solution is neutral is possible, with pH being the most common choice. A pH of 7 indicates a neutral solution, meaning it has equal concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻). However, relying solely on pH may not account for other factors, such as the presence of buffering agents, so it’s advisable to consider additional indicators for a comprehensive assessment.
How half titration could be done using only an indicator solution without PH?
In a half titration, you can use an indicator solution without needing to measure pH by adding the indicator directly to the reacting mixture and observing the color change. This can help you identify the endpoint of the titration, where half of the analyte has been neutralized. The color change will indicate the completion of the reaction, signaling that half of the titrant has been added.
What substance can best be used to determine the relative acidity of a solution?
an indicator is capable of determining if a substance is basic or acidic or neutral. if you are just looking for if it is a basic or acidic. then you could you could use red litmus or blue litmus. if you are looking for the pH of a substance try using: red cabbage indicator phenolphthalein i hope i answered your question!
How could an indicator be used to find out if something is acidic or alkline if the label was missing?
An indicator can be used to determine whether a solution is acidic or alkaline by changing color in response to the pH level of the solution. For instance, litmus paper turns red in acidic conditions (pH < 7) and blue in alkaline conditions (pH > 7). Similarly, phenolphthalein is colorless in acidic environments and turns pink in alkaline solutions. By adding the indicator to the solution and observing the color change, one can identify whether the solution is acidic or alkaline.

Could you add drops of a solution that was indicated acid into a solution that was indicated base until they became neutral?
Yes, you can add drops of an acid solution into a basic solution until they reach neutral pH. This process involves titration, where you gradually add the acid solution until the pH reaches around 7, which is neutral. It's important to use an indicator or a pH meter to monitor the pH levels during this process.

How could you use universal indicator paper as a way of distinguishing between distilled water and sodium hydroxide solution and ethanoic acid solution?
You could dip the universal indicator paper in each solution separately and observe the color change. Distilled water will not change the color significantly, indicating it is neutral. Sodium hydroxide solution will turn the paper blue or purple, indicating a strong alkaline solution. Ethanoic acid solution will turn the paper red, indicating an acidic solution.
What factors could be tested using litmus paper?
The acidity or alkalinity of a solution, pH indicator.
What is the solution called when a acid is added to alkali?
The solution could be neutral, acidic or basic depending on the concentration or the volume of the acid or alkali used.
An indicator with Ka equals 1.25 x 10-4 could be used to tell you whether a solution has a pH above or below?
A Ka value of 1.25 x 10-4 indicates a weak acid. This means that the indicator would be most effective at detecting solutions with a pH close to the pKa value of the indicator, which is approximately 3.9. Therefore, the indicator could be used to determine if a solution has a pH above or below 3.9.
Which two solutions when mixed together could form a neutral solution?
A neutral solution can be formed by mixing an equal concentration of hydrochloric acid (HCl) and sodium hydroxide (NaOH). When these two solutions are combined, they undergo a neutralization reaction to produce water (H₂O) and sodium chloride (NaCl), resulting in a solution with a pH of 7, which is considered neutral. Another example could be mixing acetic acid (CH₃COOH) with sodium acetate (CH₃COONa) in the right proportions, creating a buffered neutral solution.
What is a universal indicator changes into this color in water?
It will go green around pH 7. However because you are using universal indicator, it will be difficult to establish whether your water is completely neutral due to the variation in 'green color.' For example: one person's green could be yellow-green, another person's could be grass colored. x
