What is standard solution in titration?
A standard solution in titration is a solution of known concentration that is used to determine the concentration of another solution. It is typically a primary standard that can be accurately weighed and dissolved to make a solution of precise concentration. Standard solutions are essential in titration to accurately measure the volume of the solution being titrated and calculate its concentration.
What is the aim of titration?
To determine electrode potential
How to determine the concentration of a solution accurately?
To determine the concentration of a solution accurately, you can use techniques like titration, spectrophotometry, or gravimetric analysis. These methods involve measuring the amount of solute in a given volume of solution to calculate the concentration. It is important to follow proper procedures and use precise instruments to ensure accurate results.
Why do we need to standardize the NaOH solution?
Standardizing the NaOH solution is important to ensure its accuracy and consistency in chemical reactions and experiments. This process helps determine the exact concentration of the solution, allowing for precise and reliable results in scientific research and analysis.
Why can't a single indicator be used to tell the pH of a solution?
A single indicator cannot be used to accurately determine the pH of a solution because indicators change color over a range of pH values rather than at a specific pH. Different indicators have varying color changes at different pH ranges, so using multiple indicators or pH meters provides a more precise measure of the pH of a solution.

A scientists working in a lab wants ti determine the approximate pH of a filtered biological solution using a visual test which tool should the scientist use to measure pH?
The scientist should use pH indicator paper or pH test strips, which are designed to provide a quick visual assessment of pH levels. These tools change color depending on the acidity or alkalinity of the solution, allowing for an easy comparison against a provided color chart to determine the approximate pH. Alternatively, a pH meter could be used for more precise measurements, but it requires calibration and is not entirely visual.

What tool should you use to measure the acid?
To measure the acid concentration, a pH meter is the most accurate and effective tool. It provides precise readings of the acidity or alkalinity of a solution. Additionally, pH indicators or litmus paper can be used for a quick, qualitative assessment, but they are less precise than a pH meter. For titrations, a burette is typically used to measure the volume of acid or base added to determine concentration.

How to measure crown molding accurately for a precise installation?
To measure crown molding accurately for precise installation, use a tape measure to measure the length of each wall where the molding will be installed. Add these measurements together to determine the total length needed. Next, use a miter saw to cut the molding at the correct angles for the corners of the room. Be sure to measure and mark the molding carefully before cutting to ensure a precise fit during installation.
How would a scientist find the optimum dosage for a new drug?
They use various stages of testing to determine first a rough, then a precise effective dose and a maximum safe dose.
