determination of pH value of the unknown solution
Answers
Explanation:
The pH of the unknown solution was the pH of the test tube with which its colour corre- sponded the closest, and in this case it was test tube 6. Reading the known value of pH for test tube 6 from the table, we find that pH of the given unknown solution is 4.63.
hope it helps
Answer:
The acidic or basic property of substances is measured in terms of pH. It is a measurement of the hydrogen ion concentration.
Explanation:
If the hydrogen ion concentration is very high, the pH value is very low. This is determined using a scale ranging from 0-14 called the pH scale.
Substances with pH lower than 7 are acidic, those with pH equal to 7 are neutral and those with pH greater than 7 are basic in nature.
