The simplest ratios compare only two values, but ratios comparing three or more values are also possible. In any situations in which two or more distinct numbers or quantities are being compared, ratios are applicable. By describing quantities in relation to each other, they explain how chemical formulas can be duplicated or recipes in the kitchen expanded.
Please let me know if I’m wrong
The conversion factor is added to the original given unit so that you can end up with the final unit. Basically, the conversion unit does not change the value because the factor is just equal to 1. You just manipulate the units by cancelling them.
Among the given choices, the fraction which is equal to 1 is 10⁻³ g/ 1 mg, because there are 1,000 mg per 1 g. In reverse, that would be 10⁻³ of a gram.
Answer : The correct option is, (3) titration
Explanation :
Titration : It is a laboratory process where we have to use the volume of a solution of known concentration to determine the concentration of unknown solution.
Distillation : It is a process in which we used to separate a pure liquid from the mixture of the liquids based on the different boiling points.
Fermentation : It is a chemical process in which the the bacteria, an organism or yeast converts the carbohydrate into an alcohol or an acid.
Transmutation : It is a process in which the nucleus of a chemical elements changes into another.
Hence, the correct option is, (3) titration
Answer:
A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts.
The pH is the measure of hydrogen ion concentration in a solution. The hydrogen ion concentration at pH 1.25 is .
<h3>How to calculate hydrogen concentration?</h3>
The pH is the negative logarithmic value of the hydrogen ion concentration in the sample.
The pH can be expressed as:
The hydrogen ion concentration can be given as:
The given pH is 1.25 The hydrogen ion concentration is given as:
The hydrogen ion concentration in the solution is .
