What happens to the number of hydrogen ions if a solution becomes more acidic?
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.
Is a solution with a high pH acidic or basic?
none of them is basic...solution with ph2 is more acidic than ph3 solution.
How do you count the number of ions in a equation?
To count the number of ions in a equation you will use a net ionic equation. To start with a net ionic equation start with a balanced equation, and break all soluble strong electrolytes.
What best describes the pH number indicates about a solution?
pH is related to the activity of ions H+ in a solution. A pH under 7 is acidic, pH=7 is neutral and a pH over 7 is basic.
Why pH of 3 is concider acidic?
The whole idea of Ph value is that, in a Ph 1 compound dissolved in water, for every molecule of the acid in the solution, there is (heads up here comes the maths) X x10x10 of water molecules where X equals the number of acid molecules. If we had Ph 2 value, the equation would be this Xx10x10x10. Ph3= Xx10x10x10x10, so on and so forth. Sorry if I got anything wrong, sorry if this confuses you. I'm only in year 9. __________________________________________________________
Is NaCl acidic or alkaline and give a chemical equation to support your answer?
In solution the number of chloride ions (negative) equals the number of positive ions (sodium). NaCl -> Na+ + Cl- which is neutral in totality (neither acid nor alkaline)
What is A number that makes a equation true?
The solution set is the answers that make an equation true. So I would call it the solution.
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
When is there no solution possible to an absolute value equation and why?
For example: | x | = -1 Or any other equation where the absolute value of any expression is negative. This doesn't have a solution, because the absolute number of any expression is always positive, or zero, never negative.
What is sensible value?
A number which is reasonable.For example, an equation can have several solutions. If one solution is positive and another negative, and the quantity is a physical attribute - such as length - then the negative solution can be rejected for not being sensible.
Using the Kw equation how is it possible to determine whether an aqueous solution is acidic basic or neutral?
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
What best describes what the pH number indicates about a solution?
How acidic the solution isthe number of H+ ions in the solution
What happens to the number of hydrogen ions if a solution becomes more acidic?
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.
Is it possible for an equation to have more than one correct solution?
Definitely.The equation [ x^2 = 4 ] has two solutions.x = +2x = -2The square root of any number can be a positive number or its negative. The solution for a quadratic equation often has two different values. However having two different values is still a single solution.
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
When solving radical equations and you have a root number on one side of the equal sign and a negative number on the other side is it a no solution?
If you have an equation where a variable alone is squared and the other side is a negative, you cannot solve that equaton because it's impossible to take the square root of a negative number. So yes, it's no solution.
Number that makes an equation true?
A number that makes an equation true is its solution.
