A 'high pH number' indicates that the solution is very basic (high in the pH range of 7.1-14).

Related Information:

pH is a scale that indicates the acidity (or the lack of it) of a water system (like a swimming pool). The scale ranges from 1 (most acidic) to 14 (least acidic). 1 to 6.9 is considered acidic, 7.0 is considered neutral, and 7.1 to 14 is considered 'basic' (opposite of acidic).

An example of the significance of a high pH number, can be seen in a swimming pool. A high pH would make the pool vulnerable to an increase in bacteria and algae. This condition is controlled by the addition of hydrochloric acid (pool acid), often with bleach as well. The hydrocholric acid or bleach, lowers the pH number (increases the acidity) making the pool water much more hostile to bacteria and algae. The chlorine in the acid and bleach is a well known anti-bacterial/anti-algal agent.

What does the Richter scale tell you about an earthquake?

The Richter scale provides a measure of the magnitude or energy released by an earthquake. It quantifies the amplitude (size) of seismic waves generated by the earthquake, which correlates with the earthquake's strength. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of shaking and approximately 31.6 times more energy release.


Is a solution a homogeneous solution?

It depends on what solution you are talking about. However, generally when we say a solution we mean a homogeneous solution only. but in terms of science it is necessary to specify whether it is homogeneous or heterogeneous.


Does changing a map scale change actual distances?

No changing the map scale does not change actual distances. if you say that: 1inch = 1 mile or you say 2inches = 2 miles The scale changed but the distance between one city and the next city is still the same.


Does a protein solution have a high molarity?

No. The reason is that low molecular weight compounds tend to have high molarity. As an example NaF is 42.5 molecular weight. So 42.5g dissolved in 1 liter of water would only be 4.25% but be 1 molar. Proteins tend to have every high molecular weight. So if a protein was say 1000 molecular weight, a 10% solution would contain 100g but only be 0.1 molar.

What doe a high number on the ph scale say about a solution?

That this solution is, or contains, a strong base. A base that disassociates almost 100% in said solution.


What does a low number on a pH scale say about a solution?

The solution is an acid.


What does a number on the pH scale say about a solution?

A pH of 7 indicates it is neither acidic or alkaline, but neutral. Numbers smaller than 7 are acid, numbers higher than 7 are a base (alkaline). The further a number is away from 7, the stronger the level.


When do we say that a solution is concentrated?

A solution is said to be concentrated when it has a high proportion of the solute. There is no specific threshold at which the term comes into use.


When can you say that a number is called a solution in algebraic expression?

An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.


How would say a number that has 63 zeros?

In the short scale, 1063 - or 1 followed by 63 zeroes, is a vigintillion. In the long scale, 1063 is a thousand decillion.


What does an IQ of 114 mean?

That you are slightly above average. it is a virtual scale. there are no exact properties of the scale you can point to and say that is an example of someone with 114 IQ and say that someone with 113 IQ would not have them.In addition it is always referred to as POTENTIAL. A high IQ is not a guarantee of high intelligence unless it is exercised

How do you Use Scale in a sentence?

You didn't say which meaning of the word you wanted to use. If you mean scale as in a device to measure weight, you could say "I stepped on the scale and prayed that I had lost weight." If you mean scale like a fish or reptile has, you could say "I found a snake scale in the woods." If you mean scale like on a map, you could say "The scale of this map is one inch equals one mile." If you mean scale as in to climb, you could say "We plan to scale Mount Baldy this weekend."
