# Which solution has a pH greater than 7?

## Which solution has a pH greater than 7?

basic
The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.

## When pH value is greater than 7 it is an?

alkaline
The pH scale ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

Which of the following has pH less than 7?

Explanation: The compound (NH4) CO3 will have pH less than 7 because it will dissociate to form carbonic acid. Carbonic acid can further dissociate t form H+ ions which will further lower the pH.

### Which of the following have pH 7?

pure water has pH 7 .

### Which element has a pH of 7?

The pH scale

Increasing pH (Decreasing Acidity) Substances
7 (neutral) Water, tears
7.5 Human blood
8 Seawater
9 Baking soda, antacids

What do pH values above 7 represent?

On the pH scale, pH values below 7 represent acidic solutions (hydrogen ion activity greater than hydroxide ion activity) while values above 7 represent basic solutions. At pH = 7, hydrogen ion and hydroxide ion activity are equal (Table 1).

#### What substance has a pH greater than 7?

An acid substance has a pH of less than 7. An alkaline substance has a pH greater than 7, and a perfectly neutral substance has a pH of exactly 7.

#### What is it called when the pH is greater than 7?

pH stands for the potential of hydrogen present in liquids. The pH scale ranges from 1 to 14; neutral is 7. A pH higher than 7 is called alkaline, while a pH lower than 7 is called acidic.

What type of solution has a greater pH than 7?

At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (e.g. pure water ).
