Question

If the pH of a sample is 6.7,then the nature of sample is ___​

Answer 1

Answer:

The more acidic a solution the greater the hydrogen ion concentration and the lower the pH; a pH of 7.0 indicates neutrality, a pH of less than 7 indicates acidity, and a pH of more than 7 indicates alkalinity. The pH is used as a measure of whether the body is maintaining a normal acid-base balance

Answer 2

Answer:

The sample is slightly acidic.

Explanation:

• The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality.
• Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
• In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
• While water with more free hydroxyl ions is basic, water with more free hydrogen ions is acidic.
• Since chemicals in the water can change pH, pH is a crucial sign that the chemical composition of the water is changing.
• "Logarithmic units" are used to report pH.
• Each number corresponds to a 10-fold difference in the water's acidity or basicity.

A sample with a pH of 6.7 is acidic.
