There are 3 possible ways of determining pH.
1. A pH meter, 2. Litmus paper/ pH test strips or 3. Titrations.
1. A pH meter works by sending a small electric current through the solution. An electrical current can only be created if there are free-moving particles such as H+ ions from an acid or OH- ions from a base. The pH meter can determine the pH by how high the conductivity is.
2. Litmus Paper or pH test strips are strips that turn a specific colour under a specific pH. This colour can then be compared to a colour chart which will tell you the pH. The downfall of this method is that the red ink will stain the strip and you will be unable to get an accurate reading.
3. A titration is the best method, if done properly, for determining pH.
The ways in which ammonia can be identified is mentioned in below pointers.
<h3>What is Ammonia ?</h3>
Ammonia is a compound of nitrogen and hydrogen with the formula NH3.
A stable binary hydride, and the simplest pnictogen hydride.
Ammonia is a colourless gas with a distinct pungent smell.
Biologically, it is a common nitrogenous waste,
Three ways in which ammonia gas can be identified is:
- It has a sharp characteristic odor.
- When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.
- It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.

B, turns red litmus paper to blue
Answer:
When 2 or more pure substances are mixed together they form a mixture. If the mixture has its different components mixed evenly within the substance it is a homogeneous mixture. Whereas if the mixture has its different components mixed unevenly within the substance it is a heterogeneous mixture
