Question

The hydronium ion concentration in a sample is measured to be 1 × 10−6 M and a pH of 6. How would we classify this sample? Strong acid Neutral Weak acid Basic

Answer 1

Weak acid because 1-4 is strong acid 5-6 weak acid and 7 is neutral 8-9 weak base and 10-14 is a strong base

Answer 2

• A sample with a pH of 6 is described as a weak acid.
• The pH scale is used to describe the basicity or acidity of a sample on a logarithmic scale.
• Based on the pH value, the substances can be broadly classified as bases, acids or neutral substances.
• Further, the substances can be characterized as :
• Strong acid (pH 1-2 )
• Weak acid ( pH 3-6)
• Neutral ( pH 7)
• Weak base ( pH 9-11)
• A strong base (pH 11-14)
• Based on this, a sample with pH 6 will be a weak acid.
