A. Add the acid to water quickly and stand back in case it gets hot.
B. Wear goggles, apron and gloves then add the water to the acid and clean up any acid that splatters out.
C. Add the water to the acid and stop when the hot acid starts to splatter out.
D. Wear goggles, apron and gloves then add the acid to water slowly to let the heat dissipate.

Answer 1

To safely dilute concentrated acid, add the acid to water slowly while wearing protective gear like goggles, apron, and gloves, and stir frequently to dissipate heat.

Step-by-step explanation:

The safe procedure to use when diluting a concentrated acid with water is to always add the acid to water gradually, and not the other way around. This process should be done slowly to allow the heat of solution to dissipate and avoid any splattering which could cause harm. Wearing protective equipment like goggles, an apron, and gloves is essential to protect yourself from burns or other injuries while handling strong acids like sulfuric acid (H2SO4) or hydrochloric acid (HCl). Frequent stirring is recommended to aid in heat dissipation and to ensure a uniform mixture.
