Just the other way round:
6.8 is an ACIDIC, pH, 7.8 is a BASIC pH.
A pH of 10 is 100 times stronger (higher concentration of hydroxide ions) compared to a pH of 8. This is because the pH scale is logarithmic, where each unit change represents a tenfold difference in hydrogen ion concentration.
A solution with a pH of 7 is neutral, indicating a balance between acidic and basic properties. A solution with a pH of 9 is slightly basic, meaning it has a higher concentration of hydroxide ions compared to a neutral solution.
A pH of 3 is more acidic than a pH of 4 and a pH of 4 is more alkaline than a pH of 3. The pH balance of a swimming pool is about 7.6 meaning it is neither acidic or alkalinic, it is neutral!
The difference in strength between pH 9 and pH 4 is significant. As pH is measured on a logarithmic scale, each whole number change represents a 10-fold difference in acidity or basicity. In this case, pH 9 is 100,000 times stronger in basicity compared to pH 4.
The main difference between pH 4 and pH 6 is the concentration of hydrogen ions in the solution. A pH of 4 indicates a higher concentration of hydrogen ions compared to a pH of 6, which means the solution with pH 4 is more acidic than the solution with pH 6.
A pH 78 doesn't exist.

The pH of H2CO3 (carbonic acid) is around 3.6 at a concentration of 1 mM. This is considered a weak acid with a relatively low pH compared to strong acids.
pH paper and pH test strips are often used interchangeably to measure pH levels. They both work by changing color in response to different pH levels. However, pH test strips are typically easier to use and provide more accurate results compared to pH paper.
A pH meter or pH test strips are commonly used to measure the pH level of a solution. pH meters provide more accurate readings compared to pH test strips, which are simpler and less expensive but are less precise.
A pH of 4 is two units lower than a pH of 6, indicating a higher concentration of hydrogen ions. This means that the solution with a pH of 4 is more acidic compared to the solution with a pH of 6.
