Question

In chemistry, the pH of an aqueous solution is a measure of its acidity. The pH scale ranges from 0 to 14, inclusive. A solution with a pH of 7 is said to be neutral, a solution with a pH greater than 7 is basic, and a solution with a pH less than 7 is acidic. Write a script that will prompt the user for the pH of a solution, and will print whether it is neutral, basic, or acidic. If the user enters an invalid pH, an error message will be printed. What are the different types of design projects and what are the characteristics of each one. What are the questions that should be answered when selecting a project? In Project Selection and Needs Identification step of the Engineering Design process, what is requirements elicitation and what is its purpose?

Explanation / Answer

MATLAB Script for Q.8

clear all;
clc;

fprintf('Enter the pH value of the solution=');
pH=input('');

if pH == 7
fprintf('The solution is neutral.');
elseif pH >= 0 && pH < 7
fprintf('The solution is basic.');
elseif pH > 7 && pH <= 14
fprintf('The solution is acidic.');
else
fprintf('Error. The entered pH value is invalid.');
end
