Here's what I get  

Explanation:

A. Prepare Ca(NO₃)₂ solution

Scoopula  — to transfer the solid to an Erlenmeyer flask

Erlenmeyer flask — to hold the solid for weighing and to prepare the solution

Volumetric flask — to hold the liquid

Funnel — to transfer the solution to the volumetric flask

Wash bottle — to fill the volumetric flask to the mark

B. Weigh K₂SO₄

Scoopula  — to transfer the solid to a weighing bottle

Weighing bottle — to hold the solid for weighing.

C. Add acetic acid to a volumetric flask

Volumetric flask — to hold the acid

Pipet —to measure out the acid and transfer it to the flask

Pipet bulb — safety feature for the pipet and for control of the acid volume.

D. Add NaOH to an acid

Beaker — to hold the NaOH solution

Ring stand — to hold a buret  

Buret clamp — to hold the buret

Funnel — to transfer the solution to a buret

Buret — to hold the NaOH solution for addition to the acid

i do not get it   at all

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
