Performing an acid-base titration requires basic laboratory equipment and reagents.

• Prepare the standard solution of known concentration

• Add indicator to the solution being titrated

• Slowly add the titrant to the solution until the endpoint is reached

• Record the volume of titrant used to calculate the unknown concentration

• Equipment needed: burette, pipette, Erlenmeyer flask, stirrer, and pH meter

• Reagents needed: acid or bas

Acceleration is the rate of change of velocity over time.

• Acceleration is a measure of how quickly an object's velocity changes.

• It is calculated by dividing the change in velocity by the time taken for the change to occur.

• Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity).

• Examples of acceleration include a car speeding up from a stop sign or a ball rolling down a hill.
